Truck Trailer Gate Spring Pin Latch Barn Door Lock Spring Bolt Latch

A heavy-duty, security-critical hardware mechanism installed on the rear or side doors of freight trailers, shipping containers, and truck bodies. Its primary function is to securely lock the doors in the closed position during transit, preventing unauthorized access and ensuring cargo safety.

We produce a comprehensive range for various trailer types and door styles: Swing Door Latches, Roll-up Door Latches, Lock Rod Assemblies, High-Security Locks, ISO Container Door Locks, and Replacement Parts including handles, cams, keepers, rods, and lock cylinders.

We use robust materials to withstand heavy use and harsh weather: Main Body & Handle made of Hot-Forged or Cast Steel (grades equivalent to A36 or higher) or Stainless Steel (304/316). Locking Bolts/Cams are Hardened Steel. Springs are Stainless Steel or music wire. Finish is typically Hot-Dip Galvanized (HDG), with Powder coating or Zinc plating available.

Cam Lock: A rotating, hook-shaped bolt operated by a key. Provides a simple, keyed lock but less leverage for sealing tight doors. Paddle Handle Latch: A long lever handle connected to internal lock rods. Offers mechanical advantage for pulling doors tightly shut against seals and often incorporates a keyed lock in the handle. More common for modern freight trailers.
