The device is an anchoring point for a gas conduit grounding system. It allows electrical discharge from a gas conduit. The device is fixed in a flange hole. When the ball anchor is tightened, the spacer expands to match the diameter of the flange hole. The system is therefore integral with the flange, and grounding is possible.
Composition : • 1 extensible space • 1 threaded ring • 1 straight (or angled) ball fixpoint The threaded ring cannot be removed from the extensible spacer for each device. Only the ball fixture can be unscrewed from the assembly.
