1/2" DIA, #6 SOLID-#4 SOLID, 16 MM² STRANDED, #2 SOLID
CATALOG NUMBER
EHL12FC1K1K
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 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 Hammerlock is as easy as swinging a
hammer and requires no special tools or training. The
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.
