Universal 1U 4-Post Rack Rail for Non-Rack Equipment

This 1U rail kit mounts non-rack-mountable servers, networking gear, AV or IT equipment into a standard four-post cabinet. It suits installers who need a full-depth shelf that accepts 10" and 19" wide devices without width restrictions. The cold-rolled steel construction with electrostatic powder coat resists rust and corrosion in data-centre or office environments.

Sustained Load Behaviour with 100kg Rating

The fixed four-port design supports up to 220lbs (100kg) continuously, so heavily loaded shelves do not sag during long-term operation. Vented surfaces promote steady airflow through the rack, helping equipment maintain safe temperatures under constant load. The 42U rack-unit compatibility ensures the rails align with industry-standard mounting holes for secure, vibration-resistant attachment.

Pre-Installation Checks for Depth and Clearance

Verify that your cabinet depth falls within the 20.9" to 32" adjustable range before ordering. Confirm the rack provides four vertical posts with standard hole spacing to accept the included mounting hardware. Ensure the 1U height allocation fits your current layout and that the 3.27kg rail weight is acceptable for your floor-loading limits.

Questions about this item

How much heat builds up when the rail runs fully loaded all day?

The vented shelf design increases airflow around mounted equipment so heat dissipates continuously during 24-hour operation.

What rack width and post spacing must I already have for the 20.9-32 inch adjustable depth to fit?

The rail mounts on standard 10 inch or 19 inch four-post racks with a post-to-post distance between 20.9 and 32 inches.

Will the 100 kg cold-rolled steel rail bolt straight into my older 42U cabinet that uses the same industry-standard hole pattern?

Yes, the rail follows the 43201600 industry standard so it aligns with the mounting holes on any compliant 42U rack.
