Tripp Lite SmartRack 4-Post 1U Universal Adjustable Shelf Kit for Wall-Mount Racks

The Tripp Lite 4POSTRAILKITWM is a 1U shelf kit that brings solid, front-to-rear support to equipment inside 19 inch wall-mount racks. By creating a stable platform for up to 150 pounds (68 kilograms), it lets you secure UPS systems, power distribution units, servers, or other rectangular devices that need more than face-plate mounting alone.

Two steel rails slide to match the depth of your enclosure from 14.5 to 23.5 inches. Once set, they cradle a 17.5 inch-wide chassis while leaving the rack’s front and rear mounting holes open for cable managers, patch panels, or future gear. The structure uses cold rolled steel and carries a powder coated finish that stands up to daily wear.

This kit makes practical sense anywhere wall-mount racks are deployed—branch offices, retail back rooms, school labs, or remote network closets that lack floor space. All mounting hardware for square-hole racks ships in the box, so an installer can bolt it in and move on without a parts run.

RoHS compliance supports sustainable purchasing goals, and the five-year limited warranty helps protect your investment for the long haul.
