3U Adjustable Depth Rack Rails

These universal rack rails mount 19-inch servers or networking hardware in any standard rack. The 3U steel construction supports up to 215 lbs (97.3 kg) and fits mounting depths from 420 mm to 1054 mm. A removable rear cable management panel helps organise cables. The set includes rails, cage nuts, screws and a wrench for quick installation.

Who These Rails Suit

Installers fitting equipment between 16.5 in and 41.5 in deep will find the adjustable range covers most common chassis. Builders needing to secure gear outside that depth range or requiring tool-less sliding rails should consider other options. The fixed design does not extend for service access once mounted.

215 lbs Weight Capacity

The 97.3 kg load rating is the key figure that decides if these rails match your hardware. Verify the server or appliance weight before ordering; heavier units need rails rated above this limit.

Questions about this item

Will the 420 mm minimum depth fit my existing cabinet?

The rails adjust from 420 mm to 1054 mm, so they will fit any cabinet whose front-to-rear rail spacing falls inside that range.

Can I use the included M5 cage nuts with older rack posts that have round holes?

Yes, the 14 M5 cage nuts supplied are designed for standard square-hole posts, and the 14 M5 panel screws work with threaded round-hole posts.

How do I verify the rails are safely loaded after installation?

Confirm the equipment weight does not exceed 215 lbs, ensure all 16 pre-installed nuts and 22 screws are tight, and check that the rear cable management panel sits flush.
