1U 4-Post Rack Shelf Rails

These 1U rails install in a standard 42U rack to create a sliding shelf for servers and network gear. The set fits 19-inch, 23-inch and 30-inch cabinets and suits administrators who need a sturdy, adjustable platform for rack-mounted equipment. Each pair includes eight sets of M6 screws and cage nuts for immediate installation.

Adjustable 16-to-33-inch depth

The rails telescope from 16 inches to 33 inches, replacing fixed-depth trays that limit hardware choices. The jump is worth it when your rack depth varies between cabinets or when you plan to move heavier servers between enclosures without buying new rails. Cold-rolled steel with powder coating supports up to 110 lbs at the shortest 16-inch setting.

Check rack post spacing and thread type

Verify that your four-post rack or cabinet accepts the 16-to-33-inch range and that the vertical posts use square holes for the supplied M6 cage nuts. The rails occupy 1U of height (1.75 inches) and measure 2.83 inches wide, so confirm clearance between adjacent devices. No cover or shelf surface is included with the rails.
