Description

Overview

The 34mm zinc plated door lock kit is a heavy duty locking assembly for trailer, van and container doors using 34mm pipe. It is made from high-strength zinc plated steel and is supplied with a bolt-on keeper, giving the door lock a matching engagement point without requiring a weld-on keeper.

Features

  • Heavy duty steel construction for trailer body door hardware.
  • Zinc plated finish for exposed transport applications.
  • Designed to suit 34mm pipe.
  • Includes a bolt-on door lock keeper.

Specifications and Materials

High-strength steel construction with a zinc plated finish. The kit is sized for 34mm pipe and includes the bolt-on keeper used at the locking point.

Part number: CV1840.

Compatibility and Fitment

Confirm the existing lock uses 34mm pipe and a bolt-on keeper before ordering. A nearby 34mm zinc plated kit uses a weld-on keeper and pipe-bracket bushes instead, so check the keeper mounting method as well as pipe diameter when replacing existing door hardware.

Compliance and Safety

After fitting, check that the handle closes fully, the keeper is securely mounted and the cam action holds the door without excessive movement. Replace worn or distorted surrounding hardware that prevents full engagement.

Trailer Applications

This 34mm zinc plated door lock kit suits compatible trailer, van and container body doors where a heavy duty cam-style locking assembly and bolt-on keeper are required.

Why Choose ICS Trailers

The main ordering risk with this style of door lock is mixing up pipe diameter or keeper type. ICS Trailers can help compare the existing 34mm pipe, keeper mounting method, handle arrangement and door hardware before replacement, particularly where an older lock has been modified or repaired.

  • Match the 34mm pipe size before removing reusable door hardware.
  • Check whether the existing keeper is bolt-on or weld-on.
