CyberPower 4POSTRAIL Rackmount Rail Kit

The CyberPower 4POSTRAIL is a rackmount rail kit that helps you install 1U, 2U, and 3U equipment in a four-post rack without guesswork or improvisation. It gives you a straightforward way to line up your gear, slide it into place, and lock it down so it stays put.

Each rail adjusts from 18.5 to 29 inches, so you can fit the kit to a short communications rack or a deeper server cabinet with the same set of parts. When fully installed, the rails hold up to 231 pounds, letting you support heavy power conditioners, battery backups, or network appliances with confidence.

The rails are built from metal that resists flexing, and the kit ships with sixteen M5 x 12 screws for both the front and rear posts. That means you do not have to track down extra hardware before you get started. Slide the rails to the right length, tighten the screws, and your rack is ready for the next piece of equipment.

This kit is a practical choice for small business server rooms, campus labs, or any IT environment where the gear mix changes over time. System integrators and in-house technicians will appreciate how quickly they can swap or add devices without pulling out an entire shelf.

CyberPower covers the 4POSTRAIL with a five-year limited warranty, so you can rely on it for long-term rack builds and future upgrades.
