Read the Following Instructions
Thoroughly Before Assembly



1 Cut each cable end square and remove metal burrs. Tilt the cable downward to avoid the entry of particles into the cable.

2 Remove 2-1/8" (54 mm) of jacket from the outer conductor. Wrap paper around the cable to form a cutting guide. Clean the outer conductor with solvent.

3 Turn the threaded gasket inside out and stretch it over the end of the cable. Then flip the gasket over and screw it into position against the cable jacket.

4 Add a thin coating of silicone grease to the outer surface of the threaded gasket and the inner surfaces of the splice nut, splice body, and threaded body. Slide the splice nut onto one cable and then screw the splice body onto the outer conductor so that about 1/8" (3 mm) of the conductor protrudes. Wipe off any silicone grease from the protruding outer conductor. Install the threaded body onto the other cable in the same way as the splice body.
