Tripp Lite SmartRack Mounting Rail Kit, enables 4-Post Rackmount Installation of select UPS Systems

The Tripp Lite 4POSTRAILKITHD is a SmartRack mounting rail kit that lets you install select UPS systems and other heavy equipment in a standard four post rack. Its sliding L-bracket design adjusts from 20.5 to 36 inches, so you can match the depth of many popular rack enclosures without drilling new holes or adding extra hardware.

Each rail provides full front-to-rear support for devices with a 17.5-inch-wide rectangular chassis, and the pair holds up to 500 pounds in total. Square-hole attachment hardware is included, which means you can move from unboxing to a finished installation with the tools you already keep in the server room.

This kit is a practical choice for data centers, network closets, and branch offices where uptime matters and space is tight. System administrators who frequently reconfigure racks will appreciate the wide adjustment range, while facilities managers will value the five-year limited warranty that backs long-term reliability.
