Introducing the FL-400, everything you need in just one floor box. When you’re thinking connectivity in your floors, you should be thinking a floor box that can stand the test of time. The FL-400 challenges the thought process that you need a specific floor box for a certain floor type. With the FL-400 you get one premium floor box that can be installed in wood, concrete and raised access flooring.

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.
