When an electrical device such as a receptacle switch or the like is fixedly wired into building wiring, it is electrically and mechanically connected to an outlet box inside the wall. The device is fastened to the face of the box by screws. Ordinarily, the opening in the wall for recessing the device has minimal clearance to admit only the device and the device has extending projections that engage the wall surface around the opening so that the device mounts flush with the wall surface. When the opening is oversize, the projections pass through the opening and the workman cannot secure the receptacle firmly and mount it flush with the wall. The invention provides a set of insulated horizontal spacer members mounted parallel to one another and flexibly joined together by flimsy vertical joining elements that are readily broken apart. The workman can break off a portion of the assembly that will provide the necessary total spacing thickness and place it between the projections and the junction box. The horizontal members have an axial hole for receiving the screw that fastens the device to the box. The members are molded of a suitable insulating plastic with enough resilience so that the joining elements holding individual members apart collapse when the screw is tightened.

Spacer means for adjustably supporting an electrical device having a yoke with at least one hole for receiving a grounding and mounting screw upon a junction box with at least one screw-receiving mounting tab at a particular level with a surrounding wall surface, said spacer means comprising: (a) a plurality of substantially flat spacer members, each having a pair of broad opposed faces, said members arranged with all said faces parallel to a first plane, and each of said members having a screw-receiving aperture means for receiving a said screw passing therethrough perpendicular to said first plane; (b) flimsy connecting means connecting said members one to another with a space therebetween so as to form an elongate stack of said members with said aperture means aligned to form a channel through which a said screw my pass; (c) said connecting means constructed with a weakness for easy breaking at a selected level to provide a short stack with enough of said members to span the distance between a said yoke and a said tab when said device is at said particular level; and (d) said flimsy connecting means further constructed to deform and eliminate said space between said members when a said screw is passed through a said yoke, said members, and into a said tab and drawn up tightly. Spacer means for adjustably supporting an electrical device having a yoke with at least one hole for receiving a grounding and mounting screw upon a junction box with at least one screw-receiving mounting tab at a particular level with a surrounding wall surface and for other like spacing applications, said spacer means comprising: (a) a plurality of flat thin plates arranged in a stack, each of said plates having a pair of opposed broad faces, said plates arranged spaced apart from one another with all said faces parallel to a first plane; (b) aperture means in each of said plates for receiving a said screw, said aperture means in each plate extending between said pair of broad faces in a direction perpendicular to said plane; (c) at least two spacing members extending from each broad face of each of said plates that adjoins of said plates, said spacing members extending to the adjacent face of an adjoining plate substantially perpendicular to said broad faces and securely affixed to said broad faces, said spacing members arranged to hold said plates spaced apart from one another; (d) said spacing members having a cross-section so small relative to said plates that they are readily torn away to reduce the number of said plates in an assembly to suit a particular application, said spacing members being adapted to readily deform when compressed by a said screw to obliterate the space between adjoining plates, and in which said aperture means of all of said plates are aligned to form a channel for a said screw.
