Isolated ACE Back Boxes (ISOXXXBBX) include a galvaneal steel separation bracket mounted inside the back box to provide isolation between high and low voltage for ACE Stage Pockets. Installing ISO Back Boxes during the rough-in stage of construction saves the installer time and hassle in the finish-stage. High voltage conduit can enter the back box through combination knockouts on one side of the back box and low voltage through the opposite side. The connector and AC panels can be terminated and left inside the ISO back box until carpet is laid or floors are finished. In the final, finish stage the installer can pull the terminated connector panels through the back access opening in the ACE Pocket and secure the pocket bezel to the finished floor.

The Isolation Bracket sits tightly beneath the pocket, inside the back box, to maintain secure separation of high and low voltage, ensuring manual isolation.

ACE ISO Back Boxes are designed exclusively for use with ACE Full and Double Wide Stage Pockets. Set the back box securely braced into the floor to provide support equal to the floor loading requirements, accounting for any height offset required for the finished floor. Standard electrical conduit may be connected to the back box on any side via combination knockouts, and audio conduit connected on the opposing side. The protective cover is discarded when the finished pocket is installed. Mating screw holes are provided to secure the pocket flange to the back box flange.

Note: Not suitable for Mini or Half Back Box applications.
