StarTech.com 1U Sliding Rack Shelf 19" 14-22" Adjustable Depth 4 Post

What this shelf does and who uses it

The StarTech.com 1U sliding rack shelf mounts in a standard 19-inch cabinet and extends outward for direct access to non-rack equipment such as towers, keyboards or test gear. It occupies a single rack unit and fits four-post frames with an adjustable depth range of 14 to 22 inches. The black powder-coated steel construction suits data-centre, office or lab environments where equipment must be reachable without removal from the rack.

How the included hardware

Eight M6 screws, eight cage nuts and eight washers ship with the shelf so installers can secure it to threaded or square-hole rails without sourcing extra fasteners. The slotted vent pattern runs across the shelf surface, allowing front-to-rear airflow to pass through the unit and helping keep placed devices within thermal limits. Cold-rolled 16-gauge steel gives a rigid platform that resists flex when the shelf is fully extended.

Load capacity and depth limits

The shelf is rated for 55 pounds of evenly distributed weight, with the manufacturer noting a 60-pound maximum for the steel itself. At the shortest 14-inch setting the shelf sits close to the front posts; at the full 22-inch extension it reaches deeper cabinets but adds lever arm stress, so heavier loads should be centred and the mounting hardware checked regularly. The unit weighs 3.924 kilograms.
