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

Perfecto

Definitely a heavy duty setup. Bolted down to shed doors with 3/8 carriage bolts. Seems like the most tamper resistant setup. Definitely a bit steep on the price though.

A really secure way to lock up a building....a little tough to install, using (like I did) stainless steel carriage bolts, but once locked, you better not lose the key, unless you have a oxy-cetalene torch to cut it off. Only gripe I have is the finish....looks like simply silver paint....not powder coated for durability. As such, its already rusting where I scratched the surface slightly.

As described, strong and perfect for securing

Product made well is Easy To use. Using it for my shed/workshop door.
