Universal rack shelf rails

A 1U pair of adjustable rails fits 19, 23 and 30 inch racks and supports up to 110 lbs at the minimum depth. Cold rolled steel with powder coating provides a rigid platform for servers and network gear. Depth extends from 16.5 to 29.5 inches to match most cabinet sizes. Eight M6 screw and cage nut sets are included for quick mounting.

Verify rack and load requirements

Confirm the cabinet uses four posts with square holes spaced for M6 hardware. Measure the post-to-post depth to ensure it falls within the 16.5 to 29.5 inch adjustment range. Check that the equipment weight does not exceed 110 lbs when the rails are set at the shortest depth. Ensure 1U of vertical space is available for installation.

Replaces fixed or two-post shelves

These rails upgrade from non-adjustable trays that cannot accommodate varying chassis lengths. The adjustable depth eliminates the need for multiple shelf sizes across different cabinets. Builders who need tool-less mounting or a higher load rating at full extension will not be served by this kit.

Questions about this item

What hardware comes in the box and what must be purchased separately?

The package includes one pair of 1U server shelf rails and eight sets of M6 screws with cage nuts. No additional mounting hardware is required for standard 4-post racks.

Which depth range should I choose for my rack?

The rails adjust continuously from 16.5 to 29.5 inches deep, so a single version covers any 4-post rack within that range.

What does the 110 lb rating mean when the shelf is installed?

The 110 lb capacity applies when the rails are mounted in a 4-post rack at the minimum 16.5 inch depth; capacity may vary at deeper settings.
