Grounding Bushing System Benefits

Grounding bushings provide essential electrical safety by maintaining continuous grounding paths in conduit systems. Unlike standard locknuts, grounding bushings ensure positive electrical continuity even when mechanical connections may loosen over time. The threadless design eliminates potential threading issues while providing faster installation compared to threaded alternatives. This is particularly valuable in retrofit applications where threading may be difficult or impossible.
