The Arlington BE2 Double Gang Box Extender is used to extend the depth of an electrical box, accommodating thicker wall surfaces or deeper devices. This non-metallic extender adjusts the box depth from 1/4" to 1 1/2", providing flexibility for various installation needs. It is ideal for situations where the existing box is too shallow to fit devices such as switches, outlets, or dimmers after wall finishing. The extender is easy to install by simply attaching it to the existing electrical box, allowing for proper device alignment and safe operation. This product helps ensure that devices are securely mounted and meet code requirements, especially when wall thickness varies or when remodeling work is involved.
