Circular MIL Spec Backshells

Circular MIL Spec Backshells are designed for use on many types of military and defense electronics. They provide protection for the connecting hardware and a strain relief for the cables and wires. The MIL Spec Backshells feature a threaded coupler for attachment to the connector and a clamp or clamping ring for keeping the connector together. The MIL Spec Backshells are constructed from robust materials such as aluminum, stainless steel or plastic and are the preferred attachment solution for the harsh conditions faced in military and defense applications. The Backshells also simplify the cabling connection process and ensure a reliable connection between the device and the cable.
