400XL Puck Lock

A 400XL Puck Lock is a heavy-duty security lock designed to protect trailers, cargo doors, gates, and other equipment from unauthorized access. Its enclosed “puck” design helps shield the locking mechanism from cutting and tampering, while the hardened steel construction provides added durability and security.

Function: It secures two hasp or latch components together, preventing the door, gate, or trailer from being opened until the lock is removed with the proper key.
