I have one of these hasps and the Master round lock installed on a steel door at my remote hunting camp. it is the most secure lock and hasp that I could find. Someone tried to gain entry to my camp and beat on the lock and hasp with a hammer or some other steel tool. They put a few dings on the lock and hasp but never got in. I didn't even have to replace either the hasp or lock. A few tips, use 3/8" carriage bolts of the appropriate length ( allow for the thickness of the material being bolted to and the washer and nuts), carriage bolts are the ones with round heads that can not be removed from the outside. You may need a backer plate on the inside depending on the material that you have drilled through. A very secure heap and lock system.

Puck Lock hasp works great. Unfortunately it does not come with ⅜ carriage bolts, so don't expect to receive any. Very sturdy and worked perfectly to lock up my cab doors.

I know it was designed to use with the hockey puck lock, also designed to get you to buy the hockey puck lock. But I wanted to use a standard padlock. I got it to work, but it took more effort to get the lock inserted than I expected. Over all it is still a good purchase.

Great product very strong. Only one complaint that I have is that it did not come with nuts and bolts had to go to hardware store to go buy them. I feel that it should’ve been included.

Great hasp for Puck locks. If you purchase a master hidden hasp lock, (Puck lock) this is a must. Great price for 3.

Very solid. ***Make sure you order the correct lock diameter for this hasp. I have a bad feeling this hasp is too small for the locks I’ve ordered. I assumed it was one-size-fits-all-puck-locks. It looks small to me. I’ll soon find out...
