Master LockPadlock, Magnum Stainless Steel Lock, 2-5/16 in. Wide, M187XKAD

This is the second Master Lock Padlock that we have purchased of this type. We use them for a sliding door clasp on a public storage unit. The design prevents easy vandalism as it would be difficult to cut the lock. Several years ago there was vandalism and theft at the storage facility and several units were broken into around ours. You could see evidence of an attempt on our unit but it was left secure. Highly recommend these locks.

Seems like a good lock that is well built. Would work better for a door latch. But to use the chain for a bicycle lock but with the nature of the locking mechanism makes it cumbersome to attach to a dangling chain. Other than that it is a well-built box with appears to be very tough and dependable.

Work great

I had an old Masterlock cut off my locker at the gym (and thieves took my wallet and car key), so I was looking for something they would be really challenged to cut off. This works for that! The shaft is thicker than my old lock, and the holes in the gym's lockers are a bit small...so it's a very tight fit. But, I can make it work. I can't speak to how weatherproof it is...I'm only using it inside.

Most secure padlock I have ever used and I at one time had a store that sold padlocks among other products.

My second one. The first one survived 24/7 exposure for thirteen years in area with four seasons. Honestly, it was still solid but one key bent and plastic protective case broke (recall this thing sees all temperatures outside 24/7) so it seemed time to replace.

Fits in tight spaces

I have a lock very similiar to this, which I bought here some years ago. However, that lock's key has a black covering over the top, which is very nice and it opens better, smoother, it seems better made. This is the price to pay for everyrthing getting so expensive. Otherwise it works finee, it is just more cumbersome to take on and off.
