Custom Interface was founded in 1997 on the premise that a company can flourish by committing to treating customers, employees and vendors with respect and integrity.

Since 1997, Custom Interface, Inc., has been a world class contract manufacturer focused on custom wirecable harness manufacturing, and integrating those wire harnesses into complex electromechanical assemblies for test and measurement , renewable energy, medical, aerospace, and defense applications.

We specialize in helping our customers develop robust wire harness and cable interconnect solutions, whether it be for life-saving medical equipment, mission-critical systems for our troops abroad, or “cannot fail” equipment that operates in harsh environments.

We have attracted and retained highly talented employees and loyal customers because we have followed through on this commitment.

We have learned that we must continuously improve and adapt as our customers have trusted us with increasingly complex products and projects. We have continually grown in size and revenue because of our ability to improve and adapt.

I encourage you to consider finding out more about us.  Working with your suppliers should be a positive experience and bring profit to your company.  Although we are located in the beautiful Pacific Northwest, we aren’t just a regional resource. 

We have customers all over the world. We invite you to join them in discovering the advantage of doing business with Custom Interface.
