Ideal for secure ceiling-mounted surveillance and monitoring installations, the Peerless-AV PB-1 Plenum Box is a purpose-built ceiling mount solution that streamlines AV, security and IT deployments. Designed for use with Peerless ceiling plates (CMJ450, 453, 455 and 500), the PB-1 offers a slide-on lid for the fastest access in the industry, reducing install time in tight, low-ceiling environments. The enclosure provides 3" (76 mm) of lateral adjustment for precise camera or sensor placement and multiple mounting brackets for flexible attachment points. Built-in ½", ¾" and 1" knockouts — plus optional internal knockouts — simplify conduit routing and maintain a professional, tamper-resistant appearance. Finished in durable white fused epoxy and rated to support up to 10 lb, this plenum box keeps cable management neat while meeting RoHS standards. Backed by a 5-year limited warranty and made in the US, the PB-1 delivers a reliable, code-aware solution for security integrators, AV technicians and IT teams.
