Great for storage unit

This lock is wonderful to use on a storage unit. The other round locks that are sold to use on storage units are so hard for me to secure through the door handle. This lock has an extra long hook on it and it makes locking and unlocking the storage unit door quite easy. It's a very sturdy lock as well.

Heavy Duty Lock for securing trailer

This is a very heavy duty lock. A thief would have to be pretty determined to get it off. I use it to secure the doors on my semi truck trailer.

I thought it was a combination padlock. I don't know why only 1 key. It should have had an extra key
