For use with our FL-600P back boxes, this high-quality floor box cover has a 1/2" Brass Carpet Flange with our unique tool-less hinged U-Access door. The smaller hinged cable exit door flips back to allow the cover to remain in place after connections and cables are routed through it. The 0.25” and 0.5” raised edge style and solid covers are UL scrub water approved.
