About this item
- Patented Adjustable Shackle for a Perfect Fit This 4-digit combination lock features a patented multi-position adjustable shackle ranging from 1.57" to 3.85". Unlike fixed-shackle locks that are often too short or too loose, it delivers a snug, gap-free fit for large gates, thick door hasps, and oddly shaped locker handles where standard locks often fail.
- Enhanced Security & Durability Constructed with a high-strength zinc alloy body and a 7mm (0.27in) hardened steel shackle, this combination lock is built for cut and pry resistance. While others use thin 1/4" shackles, our 7mm shackle padlock provides superior protection for your valuables against theft and forced entry.
- 10,000 Keyless Combinations Enjoy keyless convenience with our easy-to-reset 4-digit combination system. With 10,000 unique combinations—10 times more secure than 3-digit locks—you can set your favorite numbers in seconds. No more worrying about lost keys or carrying them to the gym.
- All-Weather & Outdoor Ready Engineered for the elements, this waterproof and rust-proof padlock is perfect for both indoor and outdoor use. The premium finish protects against rain, snow, and corrosion, ensuring smooth operation on outdoor fences, backyard gates, shed doors, and storage units.
- Versatile One-Lock-for-All Solution One lock, endless possibilities. Thanks to the adjustable shackle, this versatile lock replaces multiple sizes of padlocks. Perfect for school and gym lockers, toolboxes, HASP storage, sports cases, and residential gates. A must-have security tool for students, homeowners, and travelers.

Customers praised this 4-digit combination padlock's adjustable shackle (1.57"-3.85") as "perfect" for gates, lockers, and cabinets. The zinc alloy construction feels "solid and secure" with weather-resistant design. Easy code resetting and keyless convenience were highlights. Some noted numbers are difficult to read in dim light, and the reset mechanism may be vulnerable.

I bought this lock to secure our tack stall at horse shows, and it has worked out really well. The adjustable long shackle is a huge plus because it makes it easy to fit through different latch sizes and setups without struggling.The 4 digit combination feels secure and is easy to set and remember. I also like not having to worry about keeping up with a key, especially during busy show days.It feels solid and well made, with a durable zinc alloy body that holds up well to outdoor conditions. We've used it in varying weather, and it continues to work smoothly without sticking or rusting.Overall, this is a reliable and convenient lock that gives me peace of mind when leaving our tack unattended. Definitely a great choice for shows, barns, or any outdoor use.
This is a solid lock that uses a 4-digit combo. It's very easy to set a custom combo. Just enter in the current one, flip the switch, set a new one, flip the switch back, and you're done. The build is very solid, and I like the unique long shackle on it. It adds more dimension to it that smaller shackles would limit how you can use them. It has a slim base to it and looks attractive, as well. If you need a combination padlock, this is an excellent option. Recommended.
This padlock is surprisingly robust and gives a strong first impression right out of the box. The build quality feels solid, with durable materials that inspire confidence in everyday use. Mechanically, it operates smoothly and reliably, with no sticking or hesitation when locking or unlocking.
I also appreciate the color options — mine is green — and the finish appears to be high quality. The paint has a clean, even look and seems resistant to chipping or wear, even with regular handling.
That said, there is one significant drawback that’s hard to overlook. The reset mechanism is protected by a simple Phillips head screw and a small plate. This design choice creates a potential security vulnerability, as it wouldn’t take much effort or specialized tools for someone to remove the plate, reset the combination, and gain access. For a product meant to provide security, this feels like an oversight.
If I could suggest an improvement, switching to a tamper-resistant fastener — such as a security Torx screw — would go a long way in addressing this issue. These are far less common and require specific tools, making them much more difficult for opportunistic thieves to bypass.
Overall, this is a well-made padlock with great aesthetics and solid functionality, but the reset mechanism design limits how secure it truly feels. With a small upgrade in that area, it could easily be an excellent product.
Build feels very sturdy. The body has a lot of weight to it, and the shackle feels smooth and solid. Good for gates, storage, or anything where you want quick access without dealing with keys.The dials are clear and easy to read, and they turn with a nice amount of resistance so you're not accidentally bumping them out of place.Requires a screw driver in order to toggle the set mode. That's good too if you absolutely don't want any possibility of ever accidentally changing the combo.I have other locks that require no tools at all, but I always worry how easy it is to change the combo on them as all you have to do on those is flip the loop backwards, press down, and turn the dials to set a new code.Straightforward and reliable. Does exactly what you expect.
This is one of those rare padlocks that actually solves a real?world problem instead of just repeating the same old design. The adjustable shackle is the standout feature here. Being able to dial in the exact length from 1.57 to 3.85 inches means you get a tight, secure fit whether you're locking a thick backyard gate, a fence latch with too much play, or a locker handle that never seems to match standard padlocks. No rattling, no gaps, no guessing which size to buy.Build quality is solid. The zinc alloy body feels dense and durable. The 7mm hardened steel shackle not the thicker you'll find, but it goes along with the typical quarter?inch shackles you see on most combination locks. The 4?digit system makes your life easy by not having to carry a key aropund. The reset process is straightforward.What makes this lock worth the $18.95 price is the versatility. Instead of buying multiple locks for different hasps and handle shapes, this one adapts to almost anything. For toolboxes, gym lockers, travel cases, or outdoor hardware, it's a reliable one?lock solution.
I really like this lock. My first impressions were that I was surprised by the weight and durability of the lock. It's packaged nicely and comes with easy to understand instructions. It also comes with its own mini Phillips screwdriver for unscrewing the small switch for resetting the 4 digit code. Changing to my code of choice was very easy and beats out any of those built in 3 digit "zipper locks" that can be opened so easily.The product has great size flexibility to adjust to an array of situations. The latch slides in and out with easy when unlocked and is clearly a force to be reckoned with when locked. I love how the reset switch is hidden away, but you obviously need the combo in order to utilize it. I will use this lock for a variety of purposes. Only wish they made one compatible for TSA and travel!
I got this stainless outdoor combination lock to replace a standard padlock on our gate to the back yard. This will allow contractors in and out without us being home or having to lend out a key.The shackle of the lock is adjustable, which is a plus. The diameter of the shackle is considerably less than a standard padlock, yet it still feels quite sturdy.Having a combination that can be changed as needed is much appreciated. For our purposes, we can leave it on the combo to open, where it is quickly opened and have this as part of our fire plan (we live in an area with frequent wildfires and they are sadly a constant threat).I am impressed with this item and rate it as a good find, good value.
This combination lock feels solid and well-designed for everyday security needs. It seems as though it was made from quality materials. The adjustable long shackle is a big advantage which makes it easy to fit different gate sizes, lockers, and storage hasps without struggling with spacing. The 4-digit combination system is simple to set up and offers good peace of mind compared to basic locks.The build quality feels sturdy, and the waterproof design makes it suitable for both indoor and outdoor use, even in changing weather. The dials turn smoothly, and the lock overall has a heavy-duty feel that inspires confidence for gates, fences, or toolboxes.Overall, it's a practical, reliable, and versatile lock that works well for home, school, or outdoor security needs.
This FORGE Combination Lock with Adjustable Long Shackle (1.57”–3.85”, 4-digit heavy-duty waterproof padlock, black) has been a reliable and convenient security solution for both outdoor and indoor use.
The lock feels solid and well-built, with a sturdy zinc alloy body that resists corrosion and weather. The adjustable shackle is a standout feature — it extends smoothly from 1.57” to 3.85”, giving me the flexibility to secure everything from a thin gate chain to thicker hasps on a fence, toolbox, or storage case without needing multiple locks.
Setting the 4-digit combination is quick and easy, and it stays set securely without accidental resets. The dials turn smoothly but have a satisfying click, so you don’t overshoot numbers. The waterproof design has held up perfectly through rain, snow, and humid garage conditions with no sticking or rust.
I’ve used it on my backyard gate, gym locker, and a large toolbox, and it provides solid peace of mind. The long shackle gives enough clearance for most applications, and the lock opens and closes smoothly every time.
The black finish looks clean and professional while hiding dirt and fingerprints better than shiny models. It’s compact enough to carry in a pocket or bag when needed.
If you need a tough, weather-resistant combination lock with an adjustable shackle for gates, fences, lockers, toolboxes, or outdoor storage, this FORGE padlock is an excellent choice. Highly recommend for reliable everyday security!
I'm very familiar with various combination locks. It seems a good value for the price, it's easy to use, and matches the product description. It's great quality, and I like the long height and that it's stainless steel. It comes with a small Philipps screwdriver to remove the cover for the combination reset switch. So far, haven't had any issues with it being locked, and unlocking it.
This is a heavy-duty 4-digit combination lock that I chose primarily because I wanted a keyless outdoor lock with more security flexibility than a typical 3-digit model and an adjustable shackle that could fit different types of hardware.Moving from a 3-digit to a 4-digit combination increases the possible codes from 1,000 to 10,000, which makes casual guessing much less likely. For a property gate or similar exterior access point, that extra margin of security was an important deciding factor for me.Setting the combination was straightforward using the included reset tool (a small Phillips screwdriver). The reset switch is accessed through a screw-secured port on the bottom of the lock, which helps prevent accidental or unauthorized code changes. I especially like that the code can be changed whenever needed. for example, to temporarily share access and then reset afterward.The number dials turn smoothly and click firmly into place, and there's also a solid click when the shackle opens and when it locks back into position. The dial resistance feels balanced��not loose enough to shift accidentally but not stiff to operate. The numbers are clear and easy to read against the alignment indicator, so it's easy to confirm the correct setting at a glance.I tested the dials while wearing lightweight driving-style gloves. They are still usable that way, although faster and easier to operate with bare fingers. For normal outdoor use here, that feels like a reasonable balance between security resistance and usability.The lock body has a reassuring amount of weight (about 0.4 lb) and feels sturdy rather than hollow. The zinc alloy body and 7 mm stainless steel shackle are appropriate materials for an outdoor lock in this category.One feature I found especially useful is the adjustable shackle height. It can be shortened for tighter installations which reduces exposed clearance and makes shim-style access more difficult or extended to accommodate wider gate hardware, locker loops, or toolbox handles. I tested it successfully on both a gym locker and a property gate using single-loop hardware. I wasn't able to test separated dual-loop handles, but the adjustment range (about 1.57��C3.85��) provides good flexibility for different setups. The shackle also rotates freely rather than being limited to a fixed up-and-down orientation, which makes alignment easier in real-world use.The manufacturer describes the lock as waterproof and rust-resistant for outdoor placement. I haven't owned it long enough to evaluate long-term exposure to weather, but the construction and materials appear appropriate for exterior use.Overall, this feels like a practical and well-designed keyless lock with flexible fit options and an easy reset feature. If you want an outdoor combination lock that avoids keys but still offers more security than entry-level 3-digit models, this is a solid choice. It's appropriate for deterrence-level outdoor security rather than high-security storage.
The adjustable shackle is the main reason to consider this lock, and it is genuinely useful. Being able to change the length makes it much easier to fit on gates, toolboxes, or awkward hasps where a standard fixed shackle is either too tight or leaves too much slack. Once set, it holds its position well and does not feel loose.The body feels solid enough for everyday use. It has some weight to it, and the materials seem appropriate for a general-purpose lock. The combination mechanism is straightforward to set and reset, and the dials turn with a decent amount of resistance so they do not shift accidentally.The 4-digit setup is a step up from basic 3-digit locks, but it is still in the category of convenience security rather than high-security protection. This is fine for lockers, gates, or storage where you want a deterrent, but it is not something I would rely on for high-value items.The ��waterproof�� and ��heavy-duty�� language is a bit optimistic. It should handle normal outdoor exposure, but like most combination locks, long-term weather exposure may eventually affect how smoothly the dials turn. Keeping it occasionally cleaned or lightly lubricated would help.The adjustable shackle does add complexity compared to a standard lock, so it takes a moment to understand how to set it properly the first time. After that, it is easy to use.Overall, the versatility is the standout feature here. It is a practical option if you need a lock that can adapt to different setups, as long as expectations stay in the everyday-use range rather than serious security.
Forge Combination Lock with Adjustable Long Shackle is one of those products where the design actually fixes a real-world problem instead of just offering minor variations.The standout feature is the patented adjustable shackle, which can be set anywhere from about 1.57 inches to 3.85 inches. That makes a big difference because standard padlocks are often either too short to fit properly or too loose, leaving unnecessary gaps.With this design, you can dial in a snug, secure fit whether you‘re using it on a gate, fence, locker, or toolbox.The construction feels solid and built for durability. The body is made from a zinc alloy, which provides a good balance of strength and corrosion resistance, and the shackle itself is a 7mm hardened steel.That thicker shackle is noticeable compared to typical locks that use thinner materials, and it adds an extra level of resistance against cutting or prying attempts. It gives the lock a more substantial, heavy-duty feel overall.The 4-digit combination system is another strong point. With 10,000 possible combinations, it offers significantly more security than standard 3-digit locks. Setting and resetting the code is straightforward, and the keyless design eliminates the hassle of carrying or potentially losing keys, which is especially useful for gym lockers or shared access situations.Weather resistance is clearly part of the design as well. The lock is built to handle outdoor conditions, including rain, dust, and temperature changes, without seizing up or corroding. That makes it suitable for long-term use on outdoor gates, sheds, or storage units, while still working just as well indoors.The versatility really stands out in everyday use. Because of the adjustable shackle, this one lock can replace multiple padlocks of different sizes. It works well on everything from school and gym lockers to backyard gates, toolboxes, and storage cases, which makes it a practical all-in-one solution rather than needing separate locks for different applications.Overall, the combination of adjustable fit, strong materials, higher combination security, and weather-resistant design makes this a very functional and well-thought-out lock. It��s a good value.
For those of you that require a padlock that has an adjustable shank then I definitely recommend this particular product!First of all this product is very well designed and because of the adjustable shank it allows you to utilize this lock in a lot of situations where other locks simply may not work! Therefore if you are working with a fence that has a wide locking point this adjustable shank lock will most likely be able to accommodate a situation such as this! If you have a standard gym locker or something that requires a padlock this can easily handle that as well! The adjustable shank definitely accommodates a lot of situations and gives you the flexibility and peace of mind that this lock will work for the majority of situations you may encounter!I have to say I am very impressed with the quality of the lock as everything is obviously made of good quality Steel and the components and parts look very strong & secure!Therefore, based on my review I am rating this product five stars because it really is an excellent combination padlock!?????
Lock combo is the perfect size and worked for exactly what I needed it for.
Love this lock. I used it on my back yard gate on my privacy fence to protect my dogs. The combination lock will make it quick and easy to unlock for the lawn mowers. I like the adjustable feature because I can secure the gate tighter than with a standard long shank lock.
