Ground Block Clamp for Coaxial Grounding

The PPC GBS81RWS is a UL 467 listed ground block clamp that accepts #6 through #14 AWG ground wire. It integrates an F-81 port with a weather boot to create a moisture-tight seal on every connection. The nickel-plated zinc body and 360 degree multipoint contact seizure mechanism ensure reliable electrical continuity for coaxial cable installations.

Upgrade from Basic Splitters or Ungrounded Entries

This clamp replaces simple splitters or ungrounded entry points when a code-compliant ground path and weather seal are required. The jump is worth it when shielding effectiveness must reach -140 dB minimum and return loss must stay better than -40 dB to 3 GHz. It is not for installers who only need a passive coupler without grounding or environmental protection.

Tool-Free Mounting with Standard Hardware

The raised body design allows easy access to the ground screw and mounting hardware using common hand tools. The integrated port seal seats automatically when the F-81 connector is tightened, removing the separate sealing step that often gets skipped. Corrosion resistance meets ASTM B117 salt-fog requirements, so the nickel-plated steel hardware will not seize in coastal or humid climates.

Questions about this item

What mounting hardware does the GBS81RWS include and what material is it made from?

The clamp includes nickel-plated steel mounting hardware for secure attachment to a grounding surface.

How do I install the weather boot to achieve a moisture-tight seal on the F81 port?

Slide the EPDM weather boot over the connected coaxial cable and press it firmly onto the F81 port until the integrated port seal seats completely.

When should the EPDM weather boot be replaced to maintain the moisture-tight seal?

Replace the boot if it shows cracking, hardening, or loss of elasticity, especially after prolonged exposure to temperatures near the -40°F to +140°F operating limits.
