The nVent ERICO Hammerlock irreversible mechanical connection connects the grounding conductor to the ground rod. Machined from highly conductive copper, the state-of-the-art nVent ERICO Hammerlock provides a low resistance connection designed to withstand ground fault currents and lightning transients. The connector’s mechanically rugged design will help ensure that the highest level of performance is maintained for many years after the connection has been buried in the harsh underground environment.
Installing the nVent ERICO Hammerlock is as easy as swinging a hammer and requires no special tools or training. The nVent ERICO Hammerlock can be installed three to five times faster than an acorn clamp and provides a high-quality grounding connection that is easy to use and withstands 100% of the current carrying capacity of the conductor.
