1U Universal 4-Post Rack Shelf Rails

The JINGCHENGMEI 1U shelf rails mount in any standard four-post rack or cabinet. Adjustable depth from 16.5 to 29.5 inches lets them fit a wide range of server chassis. Cold-rolled steel with powder coating supports up to 110 pounds when installed at the minimum depth.

Upgrading from fixed-depth or two-post rails

Fixed-depth rails limit chassis compatibility and often require separate kits for deeper hardware. These adjustable rails replace them when rack depth varies between 16.5 and 29.5 inches. The jump is worth it when you consolidate mixed server models in one rack row.

Tool-free depth adjustment with included hardware

Eight M6 screw-and-cage-nut sets ship with the pair, and diamond-shaped screw heads speed alignment. Rails bolt directly to front and rear posts without extra brackets. Most issues arise when rear-post spacing exceeds 29.5 inches or when load exceeds 110 pounds at full extension.
