Master Lock Puck Lock, Heavy Duty Hidden Shackle Lock and Hasp, Solid Steel Lock for Vans, M736XKAD

Great item. Doesnt come with bolts or nuts though, so thats a minus. After purchasing the extra needed nuts and bolts, it was easy to install. Very secure.

This is a really heavy duty lock. My only concern is the keys. They feel light and may break easily. Only time will tell.

I wish the lag bolts had security screws instead.

Works wells, easy to install.

Worked exactly for what I needed it for.

I love these ! Very secure set up

Soft steel. I overtightened the stainless steel carriage bolts and stripped the square cut outs turning them into circles. So my carriage bolts are loose and now I have rust streaks from the master lock rusting

Solid and heavy duty! I had it installed by a trailer supply shop, but they did not give me any indication that is was difficult or problematic to install. Pleased with it so far.

Just what I was looking for.

I have bought several sets. I installed one on a metal storage gate and it works great. I also installed one on a shipping container. They are very secure.
