Universal 1U 2U Rack Rail Kit

The CyberPower 4POSTRAIL is a universal mounting rail kit designed for 1U and 2U server equipment in four-post racks. It supports devices weighing up to 231 lb. The kit includes left and right rails plus mounting screws for immediate installation. It suits administrators deploying standard-height rack appliances.

Adjustable Depth Up To 29 Inches

Rails adjust in depth to a maximum of 29 inches (736.6 mm) to fit varying rack depths. The fixed cross-section measures 1.8 inches high by 1.5 inches wide (44.5 mm by 38.1 mm). Verify that your rack posts provide the required clearance and hole pattern before purchase. The 1.63 kg rail weight adds minimal load to the rack structure.

Simple Bolt-On Installation

Installation uses the supplied screws to bolt rails directly to rack posts; no specialised tools are required. The most common issue is misaligned post holes causing the rails to sit unevenly. Ensure the rack depth falls within the adjustable range or the rails will not reach both front and rear posts. The product has been available since 2015.
