B-line SB21B Raceway End Cap 1.5 Inches Black

Product Description

The B-LINE SB21B is a 1.5-inch end cap designed to terminate raceway runs cleanly and safely. It snaps or mounts onto the open end of compatible surface raceway channel, blocking dust, debris, and accidental contact with conductors inside. End caps are a standard finishing component in raceway installations and are installed by licensed electricians during rough-in or finish work on commercial and residential wiring projects. The black finish matches black raceway systems for a consistent, professional appearance on the completed installation.

This end cap is used to close off the terminal end of a surface-mounted raceway run wherever the channel terminates at a wall, ceiling, floor, or junction point. It is suited for indoor commercial and light industrial environments where surface raceway is used to route low-voltage or branch-circuit conductors along walls or ceilings without in-wall conduit. Electricians typically install end caps as part of a complete raceway fitting kit alongside couplings, inside corners, outside corners, and box connectors.

Key Features

• Closes the open end of 1.5-inch surface raceway channel to prevent debris entry and contact hazard
• Black finish for visual consistency with black raceway system components
• Single-piece design — sold individually (quantity per unit: 1)
• Designed for use in raceway and conduit fitting applications

Compatibility

Designed as an OEM-style fitting for 1.5-inch surface raceway systems requiring end termination. Specific raceway channel compatibility should be confirmed against the B-LINE SB-series raceway product line before installation.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements for surface raceway systems. De-energize all circuits in the raceway before handling fittings or accessing conductors. Ensure the raceway channel end is clean and free of burrs before seating the end cap. Do not force the cap onto a deformed or oversized channel end, as a poor fit may leave conductors exposed.
