The Carlon Adjust-A-Box Floor Box from Thomas & Betts features an adjustment screw that flush-mounts the box at depths from zero to 1 ¾ inches, making installation quicker and easier. Covers are available in white or ivory non-metallic material, brass and stainless steel; metallic covers include a light lacquer finish for extra protection. Each cover has two non-removable hinged doors that not only protect the unused devices from dust and scrub water, but also prevents the doors from being lost or misplaced when the devices are in use. Double-gang Carlon Adjust-A-Box Floor Boxes are dual service with the use of a dual-service divider, and offer a 34-cubic-inch capacity. Single-Gang Carlon Adjust-A-Box Floor Boxes include a duplex receptacle and offer a 20-cubic-inch capacity. Both configurations feature integral cable clamps.
