1-inch Iron Conduit Outlet Body

The Appleton Century Crofts GRT100 is a threaded iron outlet body built for 1-inch IMC conduit runs. It suits electricians and contractors pulling conductors through indoor or outdoor raceway systems. The round-back design provides a 18 cu in body capacity for splice access or directional changes. Compatible covers include the GRK series listed in the specifications.

Thermals Noise and Power Draw

As a passive iron fitting, the outlet body generates no heat, emits no noise and draws no electrical power. Its metal construction dissipates ambient temperature naturally without active cooling. Installation adds no thermal load to the conduit system. The unit operates silently in all environments.

18 cu in Body Capacity

The decisive specification is the 18 cubic inch interior volume. This capacity determines the maximum number and size of conductors permitted by code for splices, taps or bends within the fitting. Verify the fill calculation against your conductor count and gauge before selecting this outlet body. Buyers who need a larger volume must choose a different body size.

Questions about this item

How is the GRT100 conduit outlet body installed, and which step do installers often miss?

Thread the 1 in hub onto compatible threaded IMC conduit, then secure a matching GRK cover (such as GRK-1 or GRK-100C) to seal the 18 cu in body; the step often missed is tightening the cover gasket to maintain the indoor/outdoor rating.

What maintenance or replacement will this iron outlet body need over time?

The iron body itself is durable, but the GRK-series cover gasket can degrade from weather exposure; replace the cover (GRK-1, GRK-75, GRK-50, etc.) when the seal no longer compresses fully.

What limit appears first when this conduit body is used continuously in outdoor conditions?

The 18 cu in fill capacity is the first constraint — exceeding it with too many conductors makes future wire pulls difficult and can overheat the circuit.
