Locking male RCA connector. The #LRCA8 (8 mm) is designed to lock by compressing the ground crown to the chassis connector. The outer body controls the locking feature. Both coaxial and twinaxial cables are easily installed. To plug the #LRCA8 in, be sure the outer body is loose, insert the plug and rotate the outer barrel clockwise until snug. Priced per pair.
