Universal 19-inch rack shelf

The StarTech ADJSHELF is a 1U vented shelf that fits any standard 19-inch wide server rack or cabinet. It supports up to 175 lbs or 80 kg of equipment such as networking devices, KVM switches and tools. Mounting depth adjusts from 19.5 to 38.3 inches (495 to 974 mm) for flexible placement. The black steel construction adds sturdy storage without using extra rack height.

Compatibility check

Verify that your rack or cabinet accepts a 19-inch wide shelf with adjustable mounting rails spanning 495 to 974 mm. Ensure the 1U height allowance (1.6 inches or 40 mm) is available in your planned position. The internal shelf depth is 27.6 inches (700 mm) with an internal width of 17.6 inches (446 mm), so confirm your gear fits within those dimensions. No tools or proprietary brackets are required beyond the included hardware.

Upgrade path

This shelf replaces fixed-depth or non-vented trays that limit equipment placement or airflow. The adjustable depth makes the jump worthwhile when you need to mount deeper devices or align with existing rail positions in a mixed rack. It also upgrades basic wire shelves by providing a solid 175 lb surface for heavier appliances. Not suited for racks narrower than 19 inches or installations requiring more than 1U of vertical space.

Questions about this item

What comes in the box and do I need separate mounting hardware?

The shelf ships as a complete 1U vented unit with integrated adjustable brackets that slide onto standard 19 in rack rails. No extra brackets or rails are required for installation.

Should I choose a different depth version for a 700 mm deep rack?

This model covers mounting depths from 495 mm to 974 mm, so a single shelf fits racks shallower or deeper than 700 mm without needing another SKU.

Will the 175 lb rating hold a fully loaded UPS in a live rack?

The 80 kg capacity applies when the shelf is mounted across the full 19 in width with weight evenly distributed; concentrate heavy gear near the centre and verify your rack’s own load limit.
