Extenders in 3- and 4-Gang

UL/CSA Listed Box Extenders

The answer to set back electrical boxes!



Our UL and CSA Listed Box Extenders extend set back metallic or nonmetallic electrical boxes up to 1-1/2".

Made of heavy-duty, non-conductive plastic, they level and support wiring devices. And, they prevent arcing by forming a barrier between a metal box and metal side screws on the device.

Try them all for the safe and easy way to obtain UL or CSA Listed installations in set back boxes.

• Single-gang BE1 and two-gang BE2 for all standard devices, switches and GFCIs
BE1R for round or octagonal boxes

And NOW, three- and four-gang box extenders!

BE3 and BE4 for great-looking installations in set back multiple gang boxes

Arlington’s box extenders meet 2008 NEC, article 314.20 and deliver a two-hour fire rating.
