The PWB-FR-450 is a large capacity wall box with fire-resistant intumescent material within the door and its mounting frame for as much as 60 min. of protection. The box is code compliant and eliminates the need for constructing double walls. When closed, the unit’s cover is flush to the wall enabling displays to be mounted as close as possible, but also allowing ample room for other in-wall connections. The cover design has two large openings, one top and one bottom that provide convection cooling of active components and cable exits for multiple connections to the display.
