FIRESTIK R-3M Chrome Plated MEDIUM DUTY SPRING
The best way to protect your antenna, mount and vehicle from damaged caused by accidental contact is to use a spring. These springs are made from spring steel and are chrome plated. The upper and lower inserts are made of chrome-plated machine brass and have standard 3/8"-24 threads to fit all Firestik and RoadPal antennas, mounts and accessories. The medium duty model works especially well with our 2ft "KW" & "FS" series antennas as well as the 3ft "FL" or "RP" antennas.
