Eliminate access to the most vulnerable part of any padlock—the shackle. Also known as hockey puck locks, these padlocks have a completely enclosed shackle on the back for better security than standard padlocks. Designed to resist bolt-cutting and prying attacks, they’re often used on transport vans to prevent theft. Choose these locks if you want individual locks or groups of locks that open with their own key, but also open with a master key (sold separately).

Steel padlocks are chrome plated for added corrosion resistance and strength.

Add an optional hasp for a complete locking system. These hasps consist of two flanges that attach to a door and a frame or to double doors, like those on the back of a transport van. Thread the shackle through the flanges of the hasp to secure them together.
