The Phillips Industries 3-IN-1 and 4-IN-1 Electrical and Air Assemblies are designed to reduce fatigue and strain on the plug and 7-way electrical cable that can be experienced on some trailer applications where the electrical connection is higher than the air connections. The trailer side lead on the 7-way electrical cable extends out an additional 6", and the spiral wrap on the same side is reduced by 6", creating more slack on the 7-way cable. The rubber air hoses act as a shock absorber and the gladhand connections better support additional assembly pull-weight with a metal to metal connection. The combination assemblies with QCP trailer side connections provide an all-in-one electrical and air system designed for cable protection and corrosion prevention.
