Abstract

A spacer for filling the gap between an electrical mounting bracket and an electrical mounting plate of an electrical junction box and thereby enabling the bracket to be securely screwed onto the plate is dimensioned to fit between the outer ends of the bracket and the plate. The spacer includes protruding members and receptacles which are located at corresponding end portions of opposite faces thereof and which enable a plurality of spacers to be positioned on one another in a face to face relationship with the protruding members fitting into the receptacles so as to form a solid stack. Selection of the number of spacers in the stack enables the thickness of the stack to be adjusted and thereby accomodate various widths of gaps between the outer ends of the bracket and the plate. The spacer also has a centrally located hole for the mounting screw. The hole is laterally elongated to allow the screw to pass through and secure the mounting bracket to the mounting plate anywhere in the width range of the hole and thus allow the position of the spacer relative to the mounting bracket and plate to be laterally adjusted. A pair of tabs within the hole engage the screw and function to retain the screw in the hole.
