The Schroff 21130244 is a Varistar flat top cover designed for 19-inch rack systems. It features a closed construction with dimensions of 600 mm width and 900 mm depth. The unit is finished in RAL 7021 grey color, providing a standardized aesthetic for electronic enclosures. This component serves as a solid roof panel for subracks or cabinets within the PROLINE series, ensuring structural completeness and environmental protection for internal mounting rails and modules.
Verify the exact part number 21130244 against manufacturer documentation to confirm compatibility with specific rack depths. Check lifecycle status as this item may be obsolete. Ensure the required width (600W) and depth (900D) match the existing rack structure before procurement.
Select this component when a solid, non-ventilated top cover is required for a 600mm wide by 900mm deep rack assembly. Confirm that the RAL 7021 finish meets project specifications. Verify that the Varistar series mounting interface aligns with the chosen subrack model.
This part belongs to the nVent SCHROFF Varistar series, which provides modular components for 19-inch electronics packaging. The 21130 series specifically addresses rack accessories and expansion parts, allowing for customizable cabinet configurations in industrial and telecommunications environments.
Public confirmed substitute part numbers are not available in the provided documentation. As the lifecycle status is listed as Obsolete, consult the manufacturer for current equivalent models or compatible alternative top covers from the same series.
