1-inch aluminium conduit outlet body

This aluminium conduit outlet body fits 1-inch threaded IMC and provides a round-back access point for wire pulls and splices. It is rated for indoor and outdoor use and carries a body capacity of 18 cu in. Electrical contractors and maintenance teams use it to create junction points in rigid conduit runs.

Trade size 1 inch and GR cover compatibility

The single specification that determines fit is the 1-inch trade size, which matches the hub size and compatible conduit trade size exactly. Only covers from the listed GRK series — such as GRK-1, GRK-50, GRK-75 or GRK-100C — will seal this body correctly. Using any other cover size or thread type will leave the installation non-compliant.

Compatible GRK covers close the enclosure

Supplied without a cover, the body requires a matching GRK-series lid to complete the enclosure and meet code. The range includes blank, domed and gasketed variants in 50, 75 and 100 designations, letting the installer choose the profile and sealing level the site demands. Selecting the correct cover finishes the junction point and maintains the indoor/outdoor rating.

Questions about this item

What does the 18 cubic inch body capacity mean for wire fill?

The 18 cu in capacity is the maximum volume for conductors inside the outlet body; you must not exceed the fill limits in NEC Chapter 9 for the wire sizes you are pulling.

How does the 1 inch trade size and threaded IMC compatibility limit what conduit I can use?

The hub accepts 1 inch threaded IMC only; it will not fit EMT, PVC or other conduit types without the correct threaded IMC nipple or fitting.

What mounting provisions does the round back with 3 3/4 inch width and 2 7/8 inch height require?

The round back mounts to a flat surface using the two integral lug holes; allow at least 3 3/4 in width and 2 7/8 in height clearance for the body footprint.
