Blackjack
®
— Grounding Bushing
The Blackjack
®
Grounding Bushing never has
to be threaded onto a conduit. It is simply placed
in position on either a threaded or non-threaded
rigid or IMC conduit, with the grounding lug in
perfect position to accept the grounding wire —
even in tight installations.
It’s as simple as one, two, three!
Compare the installation with conventional
bushings that must be threaded onto the
conduit. In tight areas, you may have to remove
the grounding lug, keep up with the loose parts
and then reattach the lug. Then you still have
to twist and turn the bushing to get the lug
in position to accept the grounding wire.
The Blackjack bushing does away with these
needless delays for good, making it the ideal
grounding bushing — and the only logical
choice for small spaces, corners and multiple
conduit runs. And, because the grounding lug
is an integral part of the bushing, it's designed
not to fall off or get lost.

aluminum ground
wires.
Insulating nylon
surface is 150° C
rated and covers

corners.
The Blackjack
®
bushing provides
superior ground continuity.
The design of the Blackjack bushing has
an integral, cast-on grounding lug for better
ground continuity. This means that the
Blackjack bushing stands up to intense loads.
Secure grip forms
lasting bond.
The Blackjack bushing’s
cone-point mounting screw
bites securely into both
threaded and non-threaded
rigid conduits. And the
Blackjack bushing’s nylon
locking patch is designed
to prevent the screw from
loosening due to vibration.
Reduce inventory.
Because the Blackjack Grounding Bushing
is designed for threaded and non-threaded
conduits, and the ground lugs are designed to
handle an extended range, the number of parts
in inventory is reduced by up to two-thirds
without losing any application coverage.
