Overview
The Appleton T125-M is a Form 35 malleable iron Unilets conduit outlet body designed for use with 1-1/4″ rigid metal conduit (RMC) and intermediate metal conduit (IMC). This Type T body provides three hub connections, allowing electricians and system integrators to efficiently change direction, splice conductors, and add branch runs within a single fitting. The tri-coated malleable iron construction delivers high tensile strength, ductility, and superior corrosion resistance.
Key Features
- Type T three-hub configuration — accommodates multiple conduit runs in a compact footprint
- Smooth rounded integral bushings — protect conductor insulation during wire pulling and reduce sharp edges
- Tapered FNPT threads — ensure tight, rigid joints and excellent ground continuity for fault protection
- Malleable iron Form 35 construction — offers high tensile strength, impact resistance, and shock resistance
- Tri-coated finish — enhanced corrosion and abrasion resistance in demanding environments
- Pulling fitting and maintenance access — serves as pulling point for cable runs; permits conductor access for splicing and troubleshooting
