The Back Box Saver is a small reinforced Nut which can be fitted over a stripped lug. It consists of a cutout of Heat-shrink sleeving and a curved T-nut. The Back Box Saver can either be used firmly fit a socket with a stripped lug. Or to adjust the positioning of a Face plate. Installation Firstly the face plate must be removed and the wiring disconnected, making sure that power is turned off. Next enlarge the hole of the damaged lug is necessary. A T-Nut should be inserted into the cutout of sleeving and then inserted over the damaged lug so that sleeving fits around the lug and the hole of the T-Nut and the lug line up. The screws can then be replaced and the face plate can be tightened as normal. To correct the misalignment of a face plate, a pair of Back Box Savers must be fitted to the Lugs.
