The WIREMOLD COMPANY BW35 is an extra deep metal device box designed to house oversized wiring devices in residential and light commercial electrical installations. At 1.75 inches deep, it provides the additional volume needed to accommodate bulkier components without crowding connections or damaging device tails. The white finish integrates cleanly with standard wall plates. This box is installed by licensed electricians and electrical contractors as part of finished wall assemblies where standard-depth boxes are insufficient for the intended device.
The BW35 is suited for retrofit and new construction applications where oversized wiring devices must be flush-mounted in standard single-gang wall openings. Typical use cases include fan speed controls, dimmer switches, and GFCI receptacles, all of which require additional rear clearance beyond what a standard device box provides. The metal construction supports installations in locations where a steel enclosure is preferred or required by local code.
Designed as an OEM-style replacement and standard-fit device box for oversized wiring devices including fan speed controls, dimmer switches, and GFCI receptacles requiring extra depth in single-gang wall installations.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the panel and verify absence of voltage with a meter before beginning work. Secure the box firmly in the wall cavity before seating the device to ensure proper support. Do not overtighten device screws, as metal box ears can deform and prevent flush device seating.
