The FL-500P floor box is designed for conference rooms, auditoriums, courtrooms, churches and all general meeting space with concrete floors that are covered with carpet. This floor box handles power, audio, video, telecommunications and data in one elegant and practical box.The FL-500P is not only UL and CUL Listed but has also passed the latest UL test for scrub water. Because of FSR's unique engineering and manufacturing ability, FSR boxes passed for carpeted floors as well as tile and wood! The lift-off section of the cover allows full access to internal connector plates and stored cables, and the smaller hinged cable access door flips back to create the cable exit. When the box is not in use, the cover is completely closed allowing unencumbered travel in the area with only the handmitered, elegant carpet edge visible. The low profile edging is 1/4" or 1/2" high and is available in brass or aluminum. Inside the box are two angled brackets which handle standard size plates - 1 single, 1 double and 1 four gang opening. All are isolated for maximum safety. The FL-500P is designed to handle the rigors of a floor environment and still maintains flexibility and elegance.
