Middle Atlantic UMS1-5.5 1U Rack Mount Shelf 5.5 in

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND UMS1-5.5 is a 1U rack mount shelf designed to provide a stable support surface inside standard equipment racks and enclosures. At 5.5 inches deep, this shelf occupies a single rack unit of vertical space, making it a practical solution for organizing lightweight components, accessories, or passive equipment within a rack bay. It is a rackmount accessory intended for installation by AV integrators, IT professionals, electricians, and data center technicians who need organized, space-efficient rack solutions.

This shelf is suited for use in residential AV racks, commercial equipment enclosures, server rooms, and structured wiring installations. Its 1U profile keeps rack space consumption to a minimum, allowing technicians to fit more equipment in a single rack. The 5.5-inch depth accommodates smaller components that do not require a full-depth shelf, helping maintain clean cable management and airflow within the enclosure.

Key Features

• 1U rack height keeps vertical space usage minimal in standard equipment racks
• 5.5-inch depth suited for lightweight accessories and passive components
• Designed for use within standard rackmount enclosures and open-frame racks

Compatibility

Installation Notes

Installation is performed by AV integrators, IT technicians, or licensed electricians working within rack enclosures. Power down or de-energize any active equipment in the rack before installing the shelf to avoid accidental contact with energized components. Standard rack-mount hardware such as cage nuts and rack screws are typically required and should match the rack's threading standard. Follow the enclosure manufacturer's load rating guidelines and do not exceed the shelf's rated weight capacity.
