Rack shelf StarTech CABSHELFV — 2U vented steel cantilever tray, 19" rack, 16" (406×483×88 mm), 23 kg capacity, black

The StarTech CABSHELFV is a 2U vented cantilever rack shelf designed for standard 19" server racks and cabinets. Made from heavy-duty cold-rolled steel with a black finish, the tray provides a compact, fixed mounting surface 406 mm wide × 483 mm deep × 88 mm high (16" depth) and supports equipment up to 23 kg (50 lb). The vented surface promotes airflow to help manage operating temperatures for devices stored on the shelf, while the cantilever design allows installation without consuming additional front-to-back rail space.

Advantages

The shelf is constructed from commercial-grade SPCC cold-rolled steel for reliable load support and long service life. Its vented design improves ventilation for non-rackmount equipment placed on the tray, reducing heat buildup. The 2U height and 16" depth make it suitable for compact devices where a full-width rackmount unit is not required. The black finish integrates with standard rack interiors for a consistent appearance.

Suitable for

• Mounting network switches and routers that do not require full rackmount ears
• Placing small servers, storage devices or single-board computers
• Supporting UPS units, power distribution units, or battery packs
• Storing peripherals, tools, and accessories inside the rack for easy access

Key specifications

• Mounting height: 2U
• Material: commercial-grade cold-rolled steel (SPCC)
• Finish: black

• Design: cantilever/vented tray for 19" racks

How to use

Install the shelf in a compatible 19" rack or cabinet by aligning the cantilever tray with the rack's mounting rails at the desired 2U position and fastening with appropriate rack screws. Place the device centrally on the vented surface to distribute weight evenly and avoid overhanging heavy items. Ensure front and rear clearance for cables and airflow; verify that the combined weight of installed items does not exceed the specified maximum load capacity.

Usage recommendations

For optimal thermal performance, position the shelf where airflow from chassis fans or cabinet ventilation is unobstructed. Use tie-downs or Velcro straps for smaller devices to prevent movement during maintenance. If storing heavier equipment, confirm rail strength and cabinet load ratings before installation and distribute weight across multiple mounting points where possible.
