Hellermanntyton TSRI-JB3 1-gang Raceway Junction Box

Product Description

The HELLERMANNTYTON TSRI-JB3 is a 1-gang junction box designed for use with surface-mount raceway wiring systems. It provides a secure, enclosed transition point where raceway runs terminate or branch, protecting conductors and connections from mechanical damage. Electricians use this fitting to house wire splices and device connections in commercial and light industrial installations where surface raceway is the preferred wiring method. The box accommodates standard 1-gang device plates and integrates directly into compatible raceway channel assemblies.

This junction box is suited for surface raceway installations in commercial offices, retail spaces, school classrooms, and similar environments where concealed wiring is not practical. It is installed at branch points, splice locations, or end-of-run positions along the raceway run. The 1-gang form factor supports standard outlet, switch, or data device configurations when paired with the appropriate cover plate.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 386 governing surface metal and nonmetallic raceways. De-energize all circuits before opening or splicing conductors at the junction box. Secure the box to the mounting surface and verify that all conductor terminations are properly made before installing the cover. Do not exceed the fill capacity of the raceway channel or junction box enclosure.
