Switchcraft AAA Series Q-G® Easy-Install Twist Connector
The Q-G® Twist Series is available in male or female cord plug, 3 through 7 contacts. Unique features are the easy twist-on combination body/strain relief, and the reduced number of parts to assemble. With the insert built into the front shell, and the strain relief preloaded into the fluted die-cast metal body, the end user has only two parts to assemble - slide the handle onto the cable, solder the terminations, and twist on the backend. As the body is tightened, the strain relief clamps around the outer jacket of the cable.
Some say these two piece XLRs have revolutionised the audio system installation market with their time saving construction. Some say the STIG is Boris Johnson.
