Aluminium conduit outlet body 3/4in

The Appleton Century Crofts GRLB75-A is a threaded aluminium conduit outlet body sized for 3/4in trade size conduit. It suits electricians and contractors running IMC indoors or outdoors where a round-back access point is required.

Installation notes and common issues

The hub accepts 3/4in threaded IMC and mates with listed GRK-series covers such as GRK-75 or GRK-75A. A frequent error is using a cover not on the compatibility list or neglecting to seal the joint for outdoor runs.

Practical limits of the threaded interface

Threaded IMC connections rely on the 3/4in trade size for mechanical alignment and grounding continuity. The round-back profile restricts wire-bending space compared with larger trade sizes, so pulling multiple conductors through this body can be difficult.

Questions about this item

How do I confirm the GRLB75-A outlet body is installed correctly?

After mounting, verify the 3/4 in hub aligns with the threaded IMC conduit, the round back sits flush, and a compatible GRK cover (such as GRK-75 or GRK-75A) seals the opening for indoor or outdoor use.

What comes with the GRLB75-A and what must I purchase separately?

The outlet body itself is supplied; you must buy a GRK-series cover (for example GRK-75, GRK-75A or GRK-75C) and the 3/4 in threaded IMC conduit separately.

Which GRK cover should I select for the 3/4 in trade-size GRLB75-A?

Choose a cover marked for 3/4 in trade size — GRK-75, GRK-75A, GRK-75C, GRK-75U or GRK-75UA — to match the hub and conduit dimensions.
