Adjustable Rack Shelf APC AR8122BLK, metal, 470 mm width, 660 mm max depth, 44 mm height, black

APC AR8122BLK is an adjustable metal rack shelf designed for standard server racks. With a usable width of 470 mm, a maximum depth of 660 mm and a height of 44 mm, the shelf provides a stable platform for non‑rackmount equipment and accessories. The black finish matches common rack interiors and helps organize small devices, power strips, network peripherals and tools while preserving U space for rackmount items.

Advantages

The shelf is made of metal to provide durable support and resist deformation under typical IT loads. Its adjustable depth accommodates different device footprints up to 660 mm, enabling flexible placement of equipment. The 44 mm height keeps the unit compact while offering sufficient clearance for most peripherals. A black finish ensures visual uniformity inside racks and reduces light reflection.

Suitable for

• Placement of non‑rackmount servers, switches, small UPS units and network peripherals
• Mounting keyboards, monitoring consoles and KVM devices
• Storing power distribution units, cable bundles and accessories
• Temporary or permanent support where a fixed rack shelf is required

How to use

Install the shelf by aligning it with the rack’s mounting rails and fastening it at the desired height using the rack’s standard mounting hardware or the shelf’s supplied mounting brackets. Adjust the depth to accommodate the equipment footprint and ensure the shelf is level. Place devices centrally where possible to distribute weight evenly and avoid overhanging loads. Check that cables and ventilation paths remain unobstructed after installation.

Recommendations

Verify the weight of equipment to ensure it is within the shelf’s safe load capacity before installation. Use cable management to prevent strain on connected devices and maintain airflow. For heavy or vibration‑sensitive equipment, consider additional support or using dedicated rackmount shelves designed for those loads.
