From their website:
“Glenair, Inc. began operations in 1956 as the first company specifically founded to produce electrical connector accessories. Building on that foundation, we now offer a dozen, full-spectrum product lines designed to meet every interconnect requirement, including a broad range of military qualified and commercial connectors, including the MIL-DTL-38999 Series III and our ultralight Series 80 Mighty Mouse.
Glenair is a privately-held company whose strengths include ISO 9001 process quality, full-spectrum product lines, fast “turnaround” on quotes and custom orders, unsurpassed sales and technical support in every major market in the world, and the industry’s largest standing inventory of commercial and Mil-Spec electrical connector accessories.
Located in Glendale, California, our connectors, backshells and interconnect cable assemblies are all made either in America or in our facilities in Mansfield, England or Bologna, Italy. With so many interconnect manufacturers moving their production operations to Estonia, Mexico, India, China and elsewhere, Glenair is proud to continue our long-standing tradition of making our products in quality controlled plants here in the USA, or in the case of selected connector products, in Western Europe.”
