Tripp Lite 4POSTRAILSM 4-Post Rack-Mount Kit 250 lb 16.5-21.5 in

4-Post Rack Kit for Heavy UPS

The Tripp Lite 4POSTRAILSM is a side-mount installation kit that lets you secure heavy UPS units inside an EIA-standard four-post rack. Two L brackets fasten to the outer edges of the vertical mounting rails, leaving the front and rear holes free for other equipment. Hardware for square-hole rails is included in the package. It is built for administrators who need to add substantial power protection without losing rack density.

Suits 16.5-21.5 in deep racks

This kit fits racks with a mounting depth between 16.5 and 21.5 inches and supports equipment up to 17.5 inches wide. It works with compatible UPS systems as well as other heavy networking or power protection devices that match those dimensions. Buyers whose racks fall outside that depth range or whose chassis exceed the width limit cannot use this kit. Installers without square-hole vertical rails also need a different mounting method.

250 lb weight capacity on side rails

The brackets are rated to hold 250 pounds when mounted to the outside edges of the rack's vertical rails. This single load rating determines whether your specific UPS or power unit can be installed safely. Verify the equipment weight against the 250 lb limit before purchase. Exceeding the rated capacity risks structural failure and equipment damage.
