Hellermanntyton TSR3W331P Internal Corner Raceway Fitting

Product Description

The HELLERMANNTYTON TSR3W331P is an internal corner fitting designed for use with surface-mounted wire management raceway systems. It allows a raceway run to transition cleanly through an inside 90-degree wall corner, maintaining consistent cable routing and protecting wiring from abrasion at the bend point. This fitting is a hardware accessory intended for installation by electricians and low-voltage technicians during structured wiring, data, or power distribution runs. It is sold individually as a single unit and is sized to mate with 1-3/4 inch raceway channels.

Internal corner fittings like the TSR3W331P are used in commercial and residential electrical installations where surface raceway is routed along walls and must navigate inside corners. Typical applications include office wiring, data center cable management, security system wiring, and low-voltage retrofit projects where conduit is not practical. The fitting snaps or mounts into place at the corner junction to keep cable pathways neat, organized, and protected.

Installation Notes

Installation is typically performed by licensed electricians or low-voltage technicians as part of a surface raceway wiring system. De-energize all circuits in the work area before routing or securing conductors through raceway components. Ensure the raceway channel is securely fastened to the wall surface before attaching corner fittings. Follow applicable NEC guidelines for conductor fill and raceway installation in the jurisdiction of the project.
