Peerless CMJ450 Suspended Ceiling Plate

The CMJ450 Suspended Ceiling Plate from Peerless is a robust, professional-grade mounting solution crafted to deliver secure, clean, and flexible projector and equipment installations. Designed around a generous 24" x 24" ceiling tray, this plate provides a stable foundation for a wide range of AV gear while keeping cables neatly tucked away and out of sight. With four suspension tie wires anchored to the true ceiling and an additional safety cable, the CMJ450 prioritizes safety and reliability in busy environments such as classrooms, conference rooms, corporate lobbies, and entertainment venues. The built-in 1-1/2" - 11.5 NPT fitting accepts extension columns or projector mounts, enabling straightforward upgrades and adaptable configurations as needs evolve. From installation versatility to long-term maintenance, Peerless engineered the CMJ450 to stay level, durable, and easy to service, helping you achieve a polished, professional look with minimal effort.

• Large mounting surface for flexible layouts: The 24" x 24" ceiling tray provides a generous platform that supports a variety of projector sizes and AV devices. This ample surface distributes weight evenly, reducing stress on the ceiling and enabling offset or centered mounting options to suit room geometry and sightlines. It also accommodates ancillary gear like signal processors or small media controllers, all while keeping wiring concealed for a clean, professional appearance.
• Four-point suspension with redundant safety: Four tie wires suspend the tray from the true ceiling, delivering stable alignment and minimizing movement. A fifth safety cable is included to add redundancy, meeting professional safety standards and giving installers extra peace of mind in high-traffic spaces or public venues where reliability is paramount.
• Versatile mounting interface with standard NPT fitting: The 1-1/2" - 11.5 NPT threaded fitting accepts a wide range of extension columns or projector mounts, enabling quick changes to hardware without custom adapters. This common interface supports future upgrades—whether upgrading to a brighter projector, adding a replacement lens, or repositioning the setup for new room layouts.
• Compatibility and durable design for long-term use: Engineered to work with Peerless mounting ecosystems and many third-party solutions that use the same NPT standard, the CMJ450 delivers dependable interoperability. The sturdy construction and precise tolerances ensure consistent performance over time, reducing maintenance and rework during future equipment refresh cycles.
• Professional-grade aesthetics and installation confidence: Peerless is a recognized leader in AV mounting solutions, and the CMJ450 embodies this commitment with a clean, minimalist footprint that minimizes visual clutter. Its design supports easy serviceability, simple cable management, and reliable mounting so installations look as good as they perform—even in demanding venues.

How to install Peerless CMJ450 Suspended Ceiling Plate

• Step 1: Identify a true ceiling with appropriate structural anchors and confirm that the ceiling can safely support the combined weight of the CMJ450, any extension column, projector, and accessory devices. Prepare mounting points according to site requirements and local codes.
• Step 2: Attach the four suspension tie wires to the CMJ450 tray, ensuring they are evenly spaced and ready for secure attachment to the ceiling anchors. Use appropriate hardware rated for the expected load and verify that the tray remains level during this setup.
• Step 3: Secure the fifth safety cable to a designated, rated support point in the ceiling. This redundancy cable provides an additional safety measure to prevent a system failure from resulting in a dropped payload. Confirm proper tension and routing to avoid interference with the projector or other equipment.
• Step 4: Thread the extension column or projector mount into the 1-1/2" - 11.5 NPT fitting. Align the mounted hardware with your desired position and ensure compatibility with the tray’s footprint and the room’s sightlines. Tighten connections to the manufacturer's recommended torque specifications.
• Step 5: Perform a final alignment check. Verify that the tray is level and that all connections—tie wires, safety cable, and NPT fitting—are secure. If possible, perform a controlled load test in accordance with local codes and the equipment’s safety guidelines before finalizing installation and hiding cables.
