Master Lock ProSeries Combination Padlock Commercial Grade Brass Lock 1177D

Great product

Have been using this as my gym lock (overkill, I know - but as I got my laptop stolen, I'm done screwing around) - it fits with very little clearance left in the lock hole (about the width of a human hair), so its a perfect fit. You cannot move it around or yank on it very easily. It is incredibly heavy and rather intimidating looking. The brass armor shroud around it is incredibly sturdy and does a good job of making life difficult for anyone with a bolt cutter. The boron alloy shackle is also much higher quality than the standard locks you find on the shelves, with a very true metallic feel. The combination are definitely on the stiffer side - they will not easily glide like tiny padlocks. In 3 months, I have not experienced the "sticking" issue, but the tumblers definitely prefer to be turned one way, which is not really a big deal for me. It is important to note that the lock only opens one way, and the dials will get easier to move with use, but they are STIFF. Personally, I like it as it reinforces the whole tough look of the lock. The rubber bumper, which I presume is to keep the lock from scratching whatever it is rubbing against, is flimsy and I lost it on the third use. Again, not a big deal. No padlock is going to be a foolproof solution in the world of sledgehammers, shotguns, and bolt cutters - but this intimidating looking lock definitely fits the bill to help persuade a would-be thief to perhaps move onto an easier target - (or at least convince them that bringing giant bolt cutters to a gym is too risky).

Solid and work really well. Gives me a piece of mind. The combo is pretty smooth and pretty easy to set your own code.

As some others have noted, the lock can get stuck open in a situation where some or all the dials don't spin. This has happened to me twice with this lock. I researched what's going on and apparently an internal part called the hasp doesn't achieve the position it needs to be in. My lock is indoors and properly lubricated with Boeshield, and it still happens sometimes. I have fixed it by banging it on the concrete floor upside down and right side up, and I suppose the hasp slides into place and the wheels spin again, and the lock can be pressed closed. But it's definitely not the way you want the lock to be functioning. It's hard to find other brands of combination locks with the same attributes as this one, but I'm looking elsewhere, and this one is going in the garbage after a couple of months.

This lock feels heavy, sturdy, and solid - I do like it. The components fit together nicely, the mechanism operates smoothly, and the overall construction inspires confidence. Setting your own combination is straightforward, and the instructions are simple and easy to follow. One feature I particularly appreciate is the protective covering around the shackle area. It provides a bit of additional protection and makes it more difficult to access certain parts of the lock directly. While no padlock is invincible, these design choices add an extra layer of resistance against casual tampering. That said, there are a couple of minor issues. The rubber cover on the bottom tends to come loose and can be lost fairly easily. The black rubber band around the middle also feels somewhat unnecessary and could have been designed or attached more securely. As with virtually any consumer padlock, someone with the right tools, expertise, and enough determination can eventually defeat it. Master Lock products are often discussed by lock-picking enthusiasts, but the same is true for the vast majority of locks on the market. In practical terms, the purpose of a lock is usually to make unauthorized access more difficult and time-consuming, rather than to provide absolute protection. For everyday use, this lock does exactly what I expected. It's robust, easy to set up, and feels durable enough for long-term service. While a few of the rubber components could be improved, the lock itself is solid and well made. Overall, I'm satisfied with the purchase and feel it offers good value for the money.

I'm using it on my boats storage shed door. I noticed my neighbors using regular combo locks that look half as strong as this one. I'm hoping if someone does try to cut it the robustness of the case and lock will steer them to the losers around me using cheap locks...lol. This thing is built like a tank and would take more effort to get to the shackle since it is covered by the thick body. Hopefully it sends the crooks to an easier target like my neighbors locks.

Very strong and sturdy, and it’s great option for anti theft. The fit is great, and easy to use and set up. Definitely a good buy. I’ve bought multiple, they tend to last for several years.

This is a hefty lock that can provide enough deterrence to discourage theft for many uses. But, locks can always be defeated, and a padlock can only withstand just so much pounding before it fails. If I needed a secure lock for a remote location, I would go to a good locksmith and discuss the requirements before choosing a lock. For my use, my gym locker was broken into and my wallet stolen. I bought this for more secure storage. But, unfortunately, the hexagonal locking loop was too big, so I had to buy a medium security Master Lock from a local store for still-good security that would fit.

Excellent purchase
