The PWB-FR-450 is a larger capacity box that can accommodate Crestron DM-RMC-4K-SCALER-C receiver/room controller or 4 AC outlets and 4 single gang compartments. This is a fire-resistant box. The PWB-FR-450 is the only fire rated wall box in the infrastructure industry. It is designed for walls that require more opening than is allowed by code and this unique wall box eliminates the need for constructing double walls. The PWB-FR-450 complies with code and lets you hang flat screens with plenty of room for all your in-wall connections. The PWB-FR-450 is designed for applications where you need to mount larger interfaces or equipment behind a display or in any other custom application. Integrated within the cover and its mounting frame is the proper Fire Resistive Intumescent Material, providing up to 60 minutes of protection. When closed, the PWB’s cover is flush to the wall allowing a display to be mounted as close as the mounting surface will allow. The cover is ventilated top and bottom to provide convection cooling and there is a cable exit slot to pass cables from the interior of the box to a display. The covers are available in white and black. Inside the PWB-FR-450 are 4 pre-wired AC outlets and 4 single gang mounting brackets. These brackets can be removed to provide space to mount larger devices. Behind each bracket is a 3/4" and a 1" - 11/2" concentric knockout which provides ample wiring flexibility and easy installation.
