FAQ

1. What is a Truck Trailer Door Lock Latch?
A Truck Trailer Door Lock Latch is 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.

2. What types of lock latches do you manufacture?
We produce a comprehensive range for various trailer types and door styles:
Swing Door Latches: For standard rear swing doors. Include a handle, locking mechanism, and keeper/striker plate.
Roll-up Door Latches: For roll-up shutter doors, often integrated into the track system.
Lock Rod Assemblies: Complete systems with horizontal lock rods that engage multiple cam locks down the door's height.
High-Security Locks: Featuring anti-pick cylinders, shrouded shackles, or king pin locks.
ISO Container Door Locks: For standard shipping containers.
Replacement Parts: Individual handles, cams, keepers, rods, and lock cylinders.

3. What materials are used for durability?
We use robust materials to withstand heavy use and harsh weather:
Main Body & Handle: Hot-Forged or Cast Steel (grades equivalent to A36 or higher), Stainless Steel (304/316).
Locking Bolts/Cams: Hardened Steel for wear resistance.
Springs: Stainless Steel or music wire for longevity.
Finish: Hot-Dip Galvanized (HDG) is standard. Powder coating (often yellow, black, or red) and Zinc plating are also available.

4. What is the difference between a cam lock and a paddle handle latch?
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.

5.  How do I get a quote or technical support?
For a fast and accurate quote, please send:
