Corning Gilbert GF-81 Splice Barrel

The newly updated GF-81 barrel splice is a 3/8”-32 threaded coupler used by technicians to link coaxial cables together within satellite, antenna, and cable television systems. The splice barrel is specifically used with Series 59 and Series 6 cable jumpers for wall-plate and other general home-splicing applications. The nickel-plated brass body provides excellent corrosion resistance when tested for 1,000 hours in a 5 percent salt-fog environment specified by ANSI/SCTE 155.

Preferred by cable and satellite operators and installers, the GF-81 splice barrel is compatible with high-speed broadband and satellite delivery systems with superior performance through 2.4 GHz bandwidth, and is ideal for all types of coax signals: cable TV, DVR, satellite setups, etc.
