The 10URMA is a pair of rack mounting angles from the Eaton B-Line Premier series accessory line. The angles bolt inside the enclosure to give you 19 inch EIA rack rail for mounting rack-format equipment, in this case 10 rack units of usable height. It is the mounting structure only, not an enclosure and not a panel.

The 10URMA angles are UL Listed and are catalogued for Type 4 panel enclosures, so using them inside a Type 4 (watertight, dust-tight) Premier series enclosure is the intended application. They do not create the Type 4 rating themselves, the enclosure does, and drilling or cutting the enclosure to fit them is what puts that rating at risk.

Published figures are 20 inches height, 10 inches length/depth, 4 inches width, at 2.154 lb. Compare the 20 inch figure against your enclosure's interior height before ordering, since rack angles need clear vertical run plus room for the mounting hardware at top and bottom.

14 gauge steel, zinc plated. The zinc plating is a bare corrosion finish rather than a painted one, so these are meant for an inside-the-enclosure environment, not exposed architectural use.

If the gear has 19 inch rack ears, rack angles like the 10URMA are the right call, since the equipment hangs off the rails and you get 10U of stackable height. A flat back panel is the better choice for DIN rail, terminal blocks, relays and anything that bolts flat with its own hole pattern. Many installers use both in one Type 4 cabinet, angles for rack gear and a back panel behind or below it.

Eaton B-Line names these angles by rack units, and the 10URMA is the 10U version. Work out how many U your equipment stack needs, add a spare U or two for airflow and future additions, then pick the angle set that matches and confirm it fits the interior height of the enclosure you are putting it in.
