Raised Access Floor Boxes: Large


This floor box provides a practical solution for cable storage while maintaining easy access to the internal cables and connector plates.  A smaller hinged trap door folds back to create the cable exit.  The sturdy drop-in floor lip supports the unit and installs flush with the floor. The plate spacing provides a single, double and a four gang opening.

  • Mounting brackets handle standard
    electrical plates.
  • The two Internal Brackets accommodate:
    1 - Single Gang Plate
    1 - Two Gang Plate
    1 - Four Gang Plate

Each floorbox comes with a temporary cover.

Note: This floor box is only intended for carpeted floors, where the accumulation of scrub water is unlikely to occur. Additionally this box is not applicable for contact with grade.
