Shelf SCHROFF 19" Model 21130355 Full Depth 2U rack shelf

SCHROFF 19" Model 21130355 Full Depth 2U rack shelf is a heavy-duty shelf engineered for mounting equipment in standard 19-inch server and network racks. The full-depth 2U form factor delivers broad support across the rack depth, helping to secure servers, storage units, power supplies and peripherals that do not have their own rack-mount brackets or require additional stabilization. The shelf is made to integrate with industry-standard rack rails and offers a flat, stable platform for a variety of IT and industrial devices.

Advantages

The full-depth design provides consistent support from front to rear, reducing stress on mounted equipment and cabling. Constructed to align with 19" rack mounting dimensions and 2U height, the shelf simplifies installation and ensures compatibility with a wide range of racks. Its robust build improves load distribution and accessibility for maintenance tasks, while the flat surface accommodates devices of different shapes and sizes without the need for custom brackets.

Suitable for

• Mounting stand-alone servers or storage modules that lack rack ears
• Supporting power supplies, UPS modules or battery packs inside a rack
• Holding peripherals such as switches, KVMs, and external drives
• Temporary placement of diagnostic equipment during maintenance

Key specifications

• Form factor: 19" rack shelf, full depth, 2U height
• Compatibility: fits standard 19-inch server and network racks
• Surface: flat platform designed for uniform support
• Material and finish: durable metal construction with protective finish for long-term use
• Load capacity: designed for mounting typical IT and industrial devices (refer to rack manufacturer for combined load limits)

How to use

Install the shelf by aligning it with the rack's 19" mounting holes at the desired 2U position and fastening it with appropriate rack screws or cage nuts. Ensure the shelf is level and securely attached at both front and rear mounting points when available. Place equipment on the shelf so that weight is distributed evenly; for heavier devices, position them closer to the rack's mounting rails to reduce cantilever stress. Route cables neatly to prevent obstruction of ventilation and maintenance access.

Usage recommendations

Verify the rack's load rating and combine the shelf's intended device weight with other mounted equipment to ensure total load remains within safe limits. Use compatible rack hardware (screws, cage nuts, washers) and follow rack manufacturer's guidance for secure installation. For devices with significant weight or heat output, consider additional securing brackets or ventilation planning to maintain safe operation.
