Appleton Century Crofts GRLB125 conduit

1 1/4 in threaded conduit body

The Appleton GRLB125 is a threaded iron conduit outlet body built for 1 1/4 in trade-size IMC runs. It provides a secure junction point for pulling, splicing or changing direction in commercial and industrial wiring systems. Electricians and maintenance crews use it where rigid or intermediate metal conduit terminates at enclosures or equipment. The round-back GR profile fits standard GRK-series covers for a complete, code-compliant assembly.

Trade-size 1 1/4 in capacity and cover compatibility

The body accepts 1 1/4 in threaded IMC and matches the same trade-size hub, giving full wire-fill allowance for that conduit diameter. It pairs with GRK-1, GRK-2, GRK-3, GRK-50, GRK-75 and their lettered variants, so installers can select flat, domed or gasketed covers to suit the environment. The iron casting handles mechanical stress from conduit tension and impact, but it is not rated for flexible non-metallic conduit or larger trade sizes.

Iron construction for indoor and outdoor exposure

The all-iron body resists corrosion and physical abuse in damp, outdoor or wash-down locations without additional coating. Threaded hubs maintain a tight seal against moisture ingress when assembled with standard conduit sealant. No moving parts or gaskets are integral to the body itself, so long-term reliability depends on proper cover selection and installation torque. The material adds weight that requires secure mounting on the supporting structure.
