FSR is already shipping its PWB-FR-450 Wall Box. This larger-capacity expansion to the company’s PWB Wall Box family of products is the fire-rated and UL approved version of the company’s popular PWB-450.
Protected in 14-gauge steel, the PWB-FR-450 is the only fire-rated wall box in the infrastructure industry. It can accommodate Crestron DM-RMC-4K-SCALER-C receiver / room controller or four AC outlets and four single gang compartments. Additionally, 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. Complying with code, the PWB-FR-450 allows users to hang flat screens with plenty of room for all in-wall connections.
The PWB-FR-450 allows larger interfaces or equipment to be mounted behind a display or in any other custom installation. 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 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 three pre-wired AC outlets and four 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″ – 1 1⁄2″ concentric knockout which provides wiring flexibility. Here are the details.
