Application:
These extension rings with conduit knockouts
are added to junction boxes to increase wiring capacity and

Advantages::
Garvin Industries’ extension rings prevent the
need to remove old conduit boxes and wiring from circuits
when additional wiring is needed. Their bottom mounting
slots allow a quick installation onto existing boxes. Red
painted extensions rings are also available for fire alarm
circuit identification.
