Rack accessory ALLNET ALL-SMW3UGRAU metal 3U, 19 inch width 490 mm, depth 100 mm, grey

ALLNET ALL-SMW3UGRAU is a 3U metal rack accessory designed for 19" (48.3 cm) mounting systems. The unit offers a compact footprint with a 490 mm front-to-back width and 100 mm depth, finished in grey. Made from metal for mechanical strength, the accessory provides a simple housing solution for small network devices, patch panels or cable management elements inside server cabinets and network racks.

Advantages

The metal construction ensures durability and stable support for lightweight equipment while the 3U height preserves vertical rack space. The 490 mm width allows compatibility with slightly wider front panels or accessories while keeping an overall compact depth of 100 mm for installations where space behind the mounting rail is limited. The grey finish offers a neutral appearance that fits common rack environments.

Suitable for

• Mounting small network devices such as mini switches or media converters
• Housing patch panels, keystone modules or small cable managers
• Organizing power strips, adapters or accessory components inside 19" cabinets
• Use in shallow-depth racks or wall-mounted enclosures where rear clearance is limited

Key specifications

How to use

Install the accessory into a standard 19" rack by aligning the mounting holes with the rack rails and fastening with appropriate rack screws or cage nuts. Place devices, patch panels or cable organizers inside the 3U housing and secure them as required to prevent movement. Ensure that the 100 mm depth suits the intended equipment and that airflow and cable routing are not obstructed within the cabinet.

Recommendations

Use this 3U metal accessory for lightweight network components and passive equipment. Verify rear clearance in the cabinet before mounting and distribute weight evenly across the rack. For active devices that generate heat, allow sufficient ventilation and avoid blocking airflow paths.
