The nVent SCHROFF 21130322 is a rack shelf component designed for integration into Varistar CP Series cabinets. Constructed from steel with a black gray finish, this unit provides structural support within standard 19-inch equipment racks. It features a 1U height profile and specific dimensional attributes including a width of 544 mm and a depth of 479 mm. The product is part of the broader 21130 series sub-rack family, which offers varying depth options to accommodate different chassis requirements.
Verify compatibility with existing Varistar CP Series cabinets before procurement. Confirm that the 544 mm width and 479 mm depth dimensions align with your specific chassis requirements. Ensure the 1U height fits your available rack space. Cross-reference the manufacturer number 21130322 to avoid confusion with other depths in the 21130 series.
Select this model when utilizing nVent Varistar CP Series cabinets and requiring a fixed steel shelf. Consider alternative depths within the 21130 series if chassis dimensions differ. Verify that the black gray finish meets aesthetic or environmental specifications. Ensure the 1U form factor matches the vertical space constraints of the installation site.
This component belongs to the nVent SCHROFF 21130 series, which encompasses various sub-rack and shelf configurations. The series is characterized by standardized dimensions for 19-inch rack mounting. The 21130322 variant specifically addresses needs for moderate depth applications within the Varistar CP ecosystem, providing a stable platform for front-panel components.
