Rack shelf 19" 1U 254mm Delta P19/254L*P2 set of 2

Delta P19/254L*P2 is a set of two 19-inch fixed rack shelves, each occupying 1U of rack height and extending 254 mm in depth. Designed for installation in standard server cabinets and network racks, these shelves offer a compact and stable platform for mounting non-rackmount devices, small servers, network switches, routers, and other IT peripherals where full-width mounting or sliding rails are not required.

Advantages

These fixed rack shelves deliver a simple, low-profile solution that optimizes space within 19-inch cabinets. Their 1U height preserves vertical rack space while the 254 mm depth accommodates compact devices and power supplies. Made to integrate with standard rack rails, the shelves reduce vibration and provide a reliable support surface that helps maintain orderly cable routing and consistent airflow inside the cabinet.

Suitable for

• Mounting non-rackmount equipment such as external hard drives, modems and small appliances
• Installing compact switches, routers and patch panels that do not require full-depth mounting
• Creating storage space for power supplies, accessories, or spare components in server cabinets
• Supporting lab or test equipment in network closets and telecommunication racks

Key specifications

• Form factor: 19-inch rack shelf
• Unit height: 1U per shelf
• Depth: 254 mm
• Quantity: set of two identical shelves
• Mount type: fixed, front-mounted to rack rails

How to use

Install each shelf by aligning it with the rack’s 19-inch mounting rails at the desired U position and fastening with appropriate rack screws. Place devices centrally on the shelf to balance weight and avoid overhang. Ensure cables are routed to prevent strain on connectors and to maintain clear airflow. Verify that the combined load on each shelf does not exceed the rack’s or shelf’s rated capacity as specified by your cabinet manufacturer.

Usage recommendations

For stable long-term installation, use standard rack hardware and ensure shelves are secured to both front mounting points. Distribute weight evenly, avoid placing heavy point loads near the shelf edge, and maintain unobstructed ventilation around active equipment to prevent overheating.
