Abstract An electrical outlet box having improved mounting means for enabling the box to be mounted in an opening of a wall with the open front of the box being essentially flush with the front face of the wall. The mounting means includes a pair of mounting elements extending outwardly from the open front of the box for engaging the front face of the wall together with a U-shaped resilient clamping member which is mounted exteriorly of the box so as to span the box with a connecting or base portion and two depending legs which extend therefrom toward the open front of the box with the legs adapted to engage the rear face of the wall surrounding the opening therein. A connection device, such as a screw, interconnects the floor of the box with the leg connecting portion of the clamp and it serves to vary the distance between the floor of the box and the connecting portion of the clamp to cause the leg portions to move toward the front thereof and engage the rear side of the wall. The legs are provided with camming means which extend toward the side walls of the box which are provided with cooperating slots for receiving the camming means and which provides a camming action as the clamp is pulled inwardly toward the box so that the legs will cam outwardly of the box to engage the backside of the wall.
An electric outlet box for mounting in a wall opening and having first mounting means adapted to abut against a front face of a support wall through an opening of which the box is adapted to extend, second mounting means adjustably secured to the exterior of said box, said second mounting means including an essentially U-shaped member having a base portion and first and second leg portions extending therefrom in the direction of the box opening, connecting means for adjustably connecting said box with said base member for varying the distance therebetween, said first and second leg members having first and second camming means extending therefrom toward the exterior side walls of said box, said box having slots for receiving said first and second camming members when said clamp is in a first position spaced from said box and camming surfaces for said camming means as said connecting means is operated to decrease the distance between said clamp means and said box to cause said legs to bow outwardly from said box so that the ends thereof may engage the rear face of said supporting wall so as to secure said box thereto.
