Bond-Rite® CLAMP (GLM)

Self-testing grounding clamp with visual indication

The Bond-Rite CLAMP (GLM = "Ground Loop Monitoring"), patented exclusively by Newson Gale, is the only static grounding clamp that provides operators with visual verification that potentially charged equipment is connected to a verified static grounding point.

The Bond-Rite CLAMP contains a bright green LED which pulses continuously when it detects that the resistance between the equipment to be grounded and the siteís verified earth ground (e.g. copper tape) is 10 ohms or less.

Once connected, the Bond-Rite CLAMP continuously monitors the resistance of the circuit between the equipment and the verified ground point (e.g. wall-mounted bus bar).

The Bond-Rite CLAMP is an ideal solution for applications and installations where interlocks with the process are not possible.

Bright pulsing LED
Provides process operators with a visual reference point to monitor the ground status of equipment
sharp teeth
Bites through rust and contamination, to create a low-resistance connection to the earth.
