2-1/8" Deep with Conduit Knockouts
|
|
Application:
These extension rings with conduit knockouts
are added to junction boxes to increase wiring capacity and
provide access for additional conduit runs and electrical wire.
|
Advantages::
Garvin Industries’ extension rings prevent the
need to remove old conduit boxes and wiring from circuits
when additional wiring capacity is needed. Their bottom
mounting slots allow quick installation onto existing boxes.
Red painted extensions rings are also available for fire alarm
circuits. Chicago plenum boxes require double gasketed ring
#53C1-VT.
