Our square tube coupling range can support loads ranging from 750Kg to 3500Kg and have several unique features making them unique.

Overrun Damper

Unique components, bespoke to overrun coupling requirements have replaced the typical “gas strut” components. In laboratory tests the overrun damper achieved up to 40 times the life of traditional dampers, giving you peace of mind.

Oil Dampened Energy Store

The oil damping to the spring in the energy store allows gentle and progressive application of the handbrake once the handbrake has passed “over centre”.

Easy Fit Breakaway Cable

The breakaway cable is one of the most important mandatory components on the trailer. It needs regular checking and, if damaged, replacing. Cast couplings have a simple method of replacement with a clevis and pin instead of a difficult burst ring. The carabiner style front fitting allows simple attachment to a fixed point on the towing vehicle.

Cable Guide

Our couplings can be supplied with a cable guide for the breakaway cable. This is a simple pressing that can be fitted under the nut of the coupling head bolt. This guide ensures that, in the unlikely event of the trailer detaching from the towing vehicle, the breakaway cable will pull in the forward direction and apply the handbrake lever correctly.

Safety Skid

A longstanding feature on all square tube couplings, the skid is an integral feature of the square tube housing and protects the overrun lever and handbrake lever from damage from sleeping policemen and other objects under the trailer. This feature is mandatory in many European countries.
