The Arlington BE1X Plastic Extender with a larger flange is designed to correct miscut or damaged drywall around electrical boxes. It extends the depth of the box from 1/4" to 1 1/2", ensuring a proper fit for switches, outlets, or other devices after wall finishing. To use, simply attach the extender to the existing electrical box, and the larger flange covers any gaps or miscuts in the drywall around the box. This extender allows for a neat, professional finish, even when the wall opening is irregular. It's ideal for both new construction and renovation projects where drywall miscuts can occur, ensuring the box and device are properly mounted and safe.
