FSR's FL-400 Floor Boxes and Covers provide one adaptable floor box solution for wood, concrete, and raised access floor installations. With a 5-inch depth, customizable internal plates and brackets, up to 13 internal configurations, 4-gang fully divided or 5-gang semi-divided layouts, and 13 cover options, the FL-400 gives designers and installers a flexible way to deliver power, data, AV, and telecom access in commercial spaces without locking the project into one floor type.

The FL-400 includes all the necessary internal plates and brackets to make pre- and post-pour compartment changes quick and easy. Using this system, both high and low voltage gang configurations, along with compartment isolation, can be implemented “on the fly”. This makes just about any cabling/connector scenario possible. We make floor boxes that leave a lasting impression within your infrastructure.
