Anti-Rotational Connector
Thomas & Betts’ new Anti-Rotational
Connectors are designed with a rib on
the bottom that keeps the connectors
from turning, so there’s no need to
apply excessive torque and there’s no
danger of loosening connectors. The
unique “no turn” rib provides a secure
connection that eliminates conductor
pinching that results from connector
movement.
The new “no turn” design feature
solves a unique problem for electricians
and installers. Larger conductors tend
to get damaged in overtorque conditions,
and connectors are prone to loosen in
applications where there is vibration
such as motor loads. Inspectors and
local standards boards are requiring
electricians and installers to make
provisions to eliminate these condi-
tions, and Blackburn®Anti-Rotational
Connectors are the solution.
