FSR's SmartFit system is available in variety of pre-wired sub-plates. With many options to choose from, the SmartFit system provides you with a simple solution for your audio/video needs. There are two options for installation: a Fire Rated Poke Through (for existing construction), and a PVC Concrete Floor Pour Box (for new construction). Either option allows you to install multiple sub-plates that feature a universal cover assembly, giving you a consistent look throughout. Both are simple to install and include installation hardware.
