B121adj Adjust-a-box Single Gang Electrical Box, Pvc, 21 Cu In

The Carlon B121ADJ is a single-gang adjustable electrical box designed to accommodate walls of varying thicknesses. This PVC outlet box allows adjustment from 0 to 1-3/4 inches with the turn of a screw, so installers can position the box flush with different wall coverings without needing multiple box depths.

The patented design comes preset at 1/2 inch and is suitable for both new work and retrofit applications. Clip the included bracket onto any stud, then turn the adjustment screw to set the box to the correct depth. The secure bracket mounting keeps the box in place and ensures it mounts square and secure every time.
