Custom Harness

What’s the benefit to outsourcing your harness? It’s simple: you get a high quality, production-ready product at a lower cost.

Time and time again our customers tell us how much time and money they have saved by outsourcing their harness or cable assembly to DSM&T. It’s no coincidence. We at DSM&T know that no two harnesses are alike which is why our highly-trained technical sales staff treats every project as a challenge and examines the whole assembly for weak points. Combined with our years of harness assembly experience, tried-and-true production methods and industry standard connections, and you can bet you’ll have a reliable assembly that only DSM&T can bring.
