“No-turn” design keeps connector securely
in place – Even under vibration.
Blackburn
®
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 the conductor pinching
that results from connector movement.
The “no-turn” design solves a unique problem for
electricians and installers. Larger conductors tend
to get damaged in over-torque conditions, and
connectors are prone to loosen in applications
where there is vibration, such as motor loads.

Dual-rated mechanical connectors
Anti-rotational connectors
Inspectors and local standards boards are
requiring electricians and installers to make
provisions to eliminate these conditions,
and Blackburn anti-rotational connectors
are the solution.
• Unique bottom rib keeps connector from turning
• Eliminates the need for excessive torque, which
can damage large conductors
• Prevents connector loosening, even in heavy-
vibration applications
