Raised Access &
Concrete Recessed
Floor Boxes
Hubbell introduces a new series of recessed
stamped steel floor boxes for installation in
concrete and raised floor applications. These
multi-service boxes are available in four or eight
gang options and utilize "screw type" modular face
plates from the Multi-Connect recessed wall box
offering. Single gang face plate options accommodate blank, toggle, Style Line®, duplex and various
manufacturers' data connectors. One reversible
metallic cover/flange assembly mounts to both
style boxes and has been designed with a large
cable door to provide ample room for exiting
cables. Pour boxes are also available to secure
raised access floor boxes in slab grade applications.
Both the concrete and raised access floor boxes
are UL Listed for carpeted applications.
