Raxxess UNS1 Vented Universal Rack Tray Shelf
Product overview: The UNS1 is a heavy-duty 14-gauge steel shelf with a ventilated bottom designed to accommodate non-rack and half-rack components while maintaining airflow. It is intended for standard 19″ IT racks and studio racks, offering a robust mounting platform and bottom slots that improve ventilation around mounted equipment. The shelf’s vented design helps dissipate heat from devices placed on and under the shelf, supporting a cooler rack environment. This model focuses on versatility for mixed equipment and provides solid support for daily operations in data centers, studios, or server rooms.
RIVECO 2 Pack 6” Rack Shelves for 19 Inches
Product overview: Each 6” shelf provides 1U depth with vented cantilever design to support servers, IT, and audio/video gear. The shelves feature reinforced welding at the corners for load resilience and detachable mounting ears to minimize transport damage. A flip-lips design lets you orient the lips up or down—lips up protect smaller devices, while lips down suit deeper equipment. The result is a flexible, durable option suitable for compact 19″ racks and mixed equipment installs.
StarTech 1U Server Rack Shelf – 10″ Deep
Product overview: This universal 1U vented shelf fits most 19″ racks and accommodates equipment up to 10″ deep. The vented shelf enhances airflow and cooling for IT and AV gear.

Buying Guide
Key considerations when selecting half-height or cantilever shelves for a 19″ rack:
- Depth compatibility: Choose shelves with depths that match your equipment footprint to maximize airflow and minimize crowding.
- Ventilation: Prioritize vented or perforated shelves to promote cooling and prevent hotspots in dense rack environments.
- Weight capacity: Verify the shelf’s weight rating aligns with the heaviest device you intend to place, including potential future additions.
- Lip orientation and stability: Shelves with flip-up or flip-down lips provide versatility for shallow vs. deep devices and help prevent device slippage.
- Build quality: Look for reinforced corners or welded joints for durability, especially in racks that require frequent reconfiguration.
- Compatibility: Confirm the shelf is designed for standard 19″ rack systems and is suitable for IT, audio, or network equipment as needed.
- Mounting hardware: Some shelves include all necessary screws, nuts, and mounting ears—check what’s included to avoid extra sourcing.
- Disassembly option: For modular or mixed-use environments, disassembled shelves allow custom assembly to fit unique equipment arrangements.
- Depth variants: If you have a mix of shallow and deep gear, consider combinations of 7″, 8″, 10″ and 6″ shelves to optimize space and airflow.
- Mobility options: If moving racks is planned, consider shelves that align with rack rails designed for easy installation and removal, and whether casters or leveling feet are required for the cabinet.
