Great lock, Used it on my packout at work. The shackle is extra long, which in my case, made it much easier to use on my packout. They are in pristine condition, even after being on a jobsite 24/7 for the last year. They havent gotten gummed up or anything which is great.

I bought these a couple of years ago and decided to replace them since they are out in the weather. The old ones still worked, but I figured better safe than sorry and they aren't that expensive. The new ones can all keyed the same, so great, but I only got two keys with the three locks. It would have been nice to get a couple more keys. Recommended but not perfect.

I bought this lock to learn how to pick locks. From the initial look of the lock it seems to very sturdy and would be able to fit in a majority of applications. After I opened the package I verified that the keys worked and they definitely do. The lock also seemed heavy than I assumed that it would. I would assume that this would help make this lock very tough in a variety of situations.

Had a hard time finding 3 that all had the same key. I have these on my barn doors. Exposed to Upstate NY winter elements for a fee years now. Still smooth and easy to open. Heavy duty and worth every penny!

I used these on the two doors of a "Relocube" - a pod used to ship items- and they worked perfectly. The locks are heavy and seem very sturdy and durable, but open easily with the keys. Came with two keys.

We put the locks on the front gates to our side yards. They work great.

I like not needing different keys for different locks. One key opens all 3.
