Backshells and Protective Caps for 38999-Type Connectors

Backshells and caps that complete a 38999-type connector: strain relief, shield termination and protection for unmated connectors.

A connector is only as reliable as its cable exit. Backshells take the cable load off the contact joints, seal the grommet and carry the cable shield to the connector shell; protective caps keep unmated connectors clean and dry.

We make J1784 backshells and protective caps for our GJB 599 Series I to IV and J599WR connectors, in the same materials and finishes, so a complete connector set comes from one source.
