Product Improvement: Premium 3-IN-1s and 4-IN-1s with QCP™ Trailer Side Electrical Connections - Extended Lead

With a focus on our premium assemblies, all 3-IN-1 and 4-IN-1 electrical and air combination assemblies with a QCP™ trailer side electrical connection have been redesigned, as an added benefit, to relieve strain placed on the cable lead and coupled trailer 7-way electrical connection due to pull from the weight of the combination assembly on certain trailer applications. Some trailer connection applications can cause the 7-way cable to be pulled taut, especially where electrical noseboxes are higher than the coupled gladhand connections. This tension places strain on the cable and plug which can weaken the connection leading to possible continuity issues or damage to the cable at the back of the plug.

As a solution to reduce fatigue and strain on the plug and cable, the trailer side lead on the 7-way electrical cable is being extend out an additional 6 inches and the spiral wrap on this same side is being reduced 6 inches. By doing so, it creates more slack on the 7-way cable.

The gladhand connections, which are a solid mechanical means, will now better aid in the support of additional assembly pull-weight with a metal to metal connection (coupling plates). Additionally, the rubber air hoses act as a shock absorber versus the electrical cable that shouldn’t be stretched or stressed. This revision also allows for more rotation in the lines during a severe jack-knife.
