Abstract
A universal support market for attachment to the back of an electrical box, supports the box in a hollow wall structure. The support bracket at the back of the box provides a more rigid mounting to support the box when an electrical plug is pushed into or pulled from an outlet. The bracket comprises an elongate strip of sheet material, one end of the strip having a first flange extending substantially perpendicular to the elongate strip, and having attachment means therein for connection to the back of an electrical box, and a second flange at the other end of the strip, substantially parallel to the first flange, extending freom the other side of the strip to rest on the inside surface of a wall board, and at least one scored bend line across the strip such that a portion of the strip may be bent in the same direction as the second flange, and substantially parallel thereto to accommodate a different depth of electrical box and a different depth of wall structure.
