4" Deep Floor Box with Steel Temporary Construction Cover

OUR PART #  FL-500P-4-B

The FL-500P-4-B from FSR is the 4" deep version of their flashship FL-500P UL-listed floor box series.

FSR's FL-500P Floor Boxes
The FL-500P floor box combines rugged construction with an elegant design for use in carpet-, tile-, or wood-covered floors over poured concrete applications. This floor box has ample compartment room to accomodate power, audio, video, telecommunications, and data, all in one elegant and pratical box.

The FL-500P floor box 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 floor boxes pass for carpeted floors as well as tile and wood. The cover's lift-off section 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 floor box is not in use, the cover is completely closed allowing unencumbered travel in the area with only the hand-mitered, elegant carpet edge visible. The low profile edging is 1/4" or 1/2" high and is available in brass or aluminum.

The innovation continues to the "configurable" back box. The FL-500P's internal brackets can be arranged to provide numerous options for both high and low voltage standard gang openings making it the most flexible and easiest to install floor box available. The FL-500P floor box is designed to handle the rigors of a floor environment and still maintains flexibility and elegance.
