Universal 1U rack shelf kit

The Tripp Lite 4POSTRAILKIT1U is a silver rack shelf kit that occupies 1U of vertical space in a four-post enclosure. It supports up to 150 lbs. of equipment and is designed for server rooms, network closets and data centres that need a sturdy, adjustable platform.

Check rail depth and hole pattern

Verify that your cabinet uses square mounting holes and that the distance between the front and rear rails falls between 20.5 and 36 inches. The kit includes M6 screws and washers, so confirm that your existing hardware matches this thread size before installation.

Steel rails with front and rear sections

Each side consists of a front and rear rail piece that slide together to the required depth, giving a rigid frame that holds its position under load. The 3 lb. steel construction resists flex during daily use, and the included hardware secures the assembly without additional brackets.
