On the job flexibility extends to our rectangular box covers. Each 1, 2 or 3-gang cover is suitable for any wiring application and can be used with any floor surface. Nonmetallic covers are even field reversible for tile or carpet. Double door feature allows easy access to the device and helps keep stray cords organized. Carlon® rectangular floor box covers do not require a separate carpet flange. The carpet flange is part of the cover and may be removed for tile application.
