Used for Penske truck cross country move. This did the job just great. Had no issues, easy to close and open with key. VERY hefty for my needs and affordable with great quality.

Master quality, Perfect for self storage
Purchased for self storage unit I like the key retention as there’s no doubt that it’s not locked properly, also the weather strip that covers the key slot keeps snow and ice out

Keyed alike and works great
Great locks, just wish it came with 4 keys instead of 2. At least with these locks, you can get keys made for them.

I double down on a storage shed that we rented for our son. That shed will definitely be last in line for thieves. They've been working great - I like the fact that they keyhole is protected from the elements.
