The FL-710 floor box is designed for conference rooms, auditoriums, classrooms, etc. where it may be necessary to pass cables thru the box without interfering with the various connectors. This simplifies installation of wiring when a group of boxes must be connected in series. The pass thru route is front to back. The FL-710 is used on carpeted floors over concrete. This floor box provides a practical and safe solution for easy access to cables and connector plates. The lift-off section of the cover allows full access to internal cables and connector plates while a smaller, hinged trapdoor flips back to create a cable exit. All cables can be stored within the box when they are not in use, allowing unencumbered travel in the area.
