An electrical box mountable within a wall and installable from outside the wall. The box has a pan that includes a front flange for contacting an outer wall surface that extends outwardly from a sidewall. A back bracket is positioned opposite the front flange and adjacent to the back wall and a fastener having a shaft extends through the back wall to movably secure the back bracket to the back wall. No portion of the shaft extends behind the back bracket. The back bracket is movable relative to the pan between a first position adjacent to the back wall and a second position spaced farther from the back wall. The bracket and front flange are adapted for clamping a portion of a wall located between the front flange and back bracket when the back bracket is in its first position.
