ReceptXtenders™ were the original non-metallic box extender utilizing a simple mounting method. Other extension devices required complicated additional attachment means prior to attaching the receptacle to the extender.  ReceptXtenders™ use the two existing holes in the receptacle box as the means to mount the ReceptXtenders™ and then the receptacle. Previously, this means of attachment was not allowed by UL. We lobbied hard to convince UL how important it was to have a simple device that every electrician and home remodeler would use. UL finally decided we were right and after extensive testing, ReceptXtenders™ were one of the first to be granted the coveted UL Listing. The patented rear flange allows our device to fit perfectly and snugly against every type of receptacle box both metallic and non-metallic. Since ReceptXtenders™ are the only receptacle box extension device to completely seal around the perimeter of the existing box we believe ReceptXtenders™ are the only device that truly meets NEC 370-20 and 370-22 that requires the box to be flush with the surface of combustionable wall surfaces. Adjustable, telescoping devices leave gaps around the perimeter of the box and some are actually made of combustionable materials such as polypropylene. Ever wonder why their device is not UL approved?

ReceptXtenders™ box extenders are made in the USA of the finest UL approved flame retardant materials. Our UL file QCMZ.E174133 lists ReceptXtenders™ as an approved device.
