3-Gang Box Extender with Larger Flange for Oversized Wall Openings
The Arlington BE3X 3-Gang Box Extender is designed to bring recessed electrical boxes flush with the finished wall surface while providing additional device support in oversized or miscut wall openings. Its larger perforated flange offers improved stability for switches, receptacles, and GFCIs, while remaining trimmable for use with standard wall plates or accommodating midi and jumbo cover plates. The extender adjusts electrical boxes set back up to 1-1/2 inches, helping installers comply with NEC Article 314.20 for flush-mounted electrical devices. :contentReference[oaicite:0]{index=0}
Manufactured from durable flame-retardant non-conductive plastic, the BE3X creates a protective barrier between device screws and metal boxes to help prevent arcing and short circuits. It is UL listed with a 2-hour fire rating and works with most steel and non-metallic outlet boxes, making it an ideal solution for remodeling, drywall repairs, tile installations, and new construction where wall finishes increase box setback. :contentReference[oaicite:1]{index=1}
