Abstract
An adjustable electrical box assembly for providing electrical service on a brick or stone wall. The assembly includes a base member, anchoring members, and an electrical box. The base member includes sidewalls with a plurality of outward extending tabs and a top wall with a forward extending lip. The anchoring members are substantially L-shaped with a first leg for anchoring against the substrate of a structure and a second leg for securing to the sidewalls of the base member. The electrical box assembly enables easy mounting and leveling of an electrical fixture either flush with or at some predetermined offset from a brick or stone wall.
