Custom Wire Harnesses
We design and manufacture complex wire harnesses engineered for durability in extreme conditions. Our solutions serve aerospace, defense, and industrial clients requiring precision and reliability. Each harness is built to exact specifications, ensuring seamless integration and long-term performance in harsh environments.
Custom Overmolding
Our overmolding process enhances cable assembly durability by encapsulating connectors in protective materials. This method improves strain relief, environmental resistance, and aesthetic consistency. Clients benefit from reduced failure rates and extended product lifespans in demanding applications.
Custom Cable Assemblies
We produce shielded, multi-conductor cable assemblies tailored to specific electrical and mechanical requirements. Our assemblies meet rigorous industry standards, supporting critical infrastructure in telecommunications, medical, and energy sectors with superior signal integrity and mechanical strength.
Custom Box Builds
Our box builds integrate wiring harnesses, cable assemblies, and electronic components into rugged enclosures. These systems provide organized, protected solutions for control panels, data transmission, and power distribution in challenging operational environments.
Special Projects
We tackle unique challenges through specialized manufacturing projects, including seismic data cables with steel braiding and overmolded connectors for pest resistance. Our team collaborates closely with clients to develop innovative, field-tested solutions for niche applications.

Reply to BeeCee comment : very funny! "small purchases ... should go to local hardware store" -- Oh yah ! Local hardware stores do not sell electronic parts ... It is almost impossible to find any such local retailer of electronic parts anymore, and the photo from their store looks like a retailer.

I've found these guys to be accommodating, friendly, and professional. I think they are geared towards industry folk. So people walking in looking for an adapter or a little one off consumer type thing may be put off. They only service business accounts now. They offer quality product that you won't find at say, Lee's Electronic (nothing against Lee's, love those guys, bit they are more consumer based, not pro based) if you are looking for pro level product for meeting specific industrial ratings, this is the place to go. RP was ok but unfortunately they dropped the ball a couple of times when

Uummm... Quite a number of negative reviews here. That many people can't be wrong. I was here yesterday and was treated very badly. Blank stare in the tall man's face. All I'm looking for is a plug! If you don't want public walk ins and only look for wholesale business then put a sign on the door... We don't want your money public people.

I buy my supplies here, great selection and service.
poor reviews are generally from people with very small purchases that should be shopping at retail hardware stores instead of wholesale distributors
