CyberPower CRA50006 19 in 1U Heavy-Duty Shelf, 135 lb | 4-Post Rack

Put heavier gear where it belongs: securely inside the rack. The CyberPower CRA50006 is a 19 in, 1U heavy-duty shelf designed for 4-post rack environments, giving you a stable platform for equipment that does not ship with rack ears or a native mounting kit. With a 135 lb load capacity, it is built for real infrastructure use, not light-duty accessory duty. Its adjustable 20.6-41.6 in depth range helps it fit a wide span of cabinet layouts, which is valuable when standardizing shelf inventory across multiple rack depths. That flexibility reduces the need to source different shelves for different rooms or deployments. The 1U profile preserves vertical space, while the heavy-duty construction supports denser and more valuable equipment without sag or instability. For teams that need to mount appliances, small servers, test gear, or network peripherals cleanly and safely, this shelf adds order to the rack and protects equipment from improvised placement. It is a straightforward component, but one that matters when uptime, serviceability, and physical support all have to hold together.
