Universal 19-Inch Rack Shelf

This 1U cantilever shelf mounts into any standard 19-inch rack or cabinet to hold IT, network, or AV equipment. Its six-inch depth suits shallow devices such as patch panels, small switches, or audio processors. The unit occupies a single rack unit and ships with 10-32 screws, washers, and cage nuts for immediate installation.

Vented Cold-Rolled Steel Build

Heavy-duty 2.4mm SPCC cold rolled steel supports up to 40 pounds, which is 70 percent more capacity than typical cantilever shelves. A matte-black powder coat resists scratches and corrosion in dense equipment rooms. Precision vent patterns promote front-to-rear airflow while preserving structural rigidity, helping prevent hot spots around mounted gear.

Upgrade From Shallow Fixed Trays

The cantilever design replaces fixed-depth trays that waste space or block rear-cable routing on four-post racks. Installers gain the 40-pound rating without needing rear mounting rails, freeing depth for cable managers or power strips. The jump is worthwhile when equipment weighs more than legacy shelves allow or when airflow through the shelf itself becomes a cooling priority.
