Hubbell Wiring Device-kellems HBL57513IVA 3 Gang Extension Box

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL57513IVA is a 3-gang extension box designed for use with surface-mount raceway wiring systems. It mounts directly to compatible Hubbell raceways and provides the added depth and gang space needed to house standard electrical devices such as receptacles, switches, or low-voltage inserts. The rectangular housing measures 6.45 inches in length, 4.54 inches in height, and 1 inch in depth, making it a compact but functional addition to structured wiring layouts. Electricians and facilities maintenance professionals install this fitting when device mounting depth or gang count exceeds what the base raceway channel provides.

This extension box is suited for commercial, institutional, and light industrial environments where surface raceway systems deliver power and data along walls without cutting into finished surfaces. It is commonly installed in office build-outs, healthcare facilities, classrooms, and retrofit wiring projects where in-wall rough-in is not practical. The 3-gang configuration supports multiple device combinations within a single fitting footprint, reducing the number of individual raceway outlets required along a run.
