Complete upper enclosure coverage on a 23 EIA AQR rack configuration with a black top panel assembly sized for 36.42 in / 925 mm depth. The panel occupies the rack top position and gives installers a correctly dimensioned enclosure component rather than a generic panel intended for another rack width or depth. TS1031031 is specified for the 23 EIA AQR configuration. That compatibility designation matters when completing or servicing a rack assembly because top panels must correspond to the enclosure geometry they join. Its 36.42 in / 925 mm depth designation identifies the intended cabinet depth, while the black finish supports a consistent appearance with matching rack components. Use this assembly when the rack requires a replacement or completion top panel at the stated EIA width and depth. Verify the installed enclosure uses the 23 EIA AQR configuration and 925 mm depth before selection. The product is a top panel assembly, not a freestanding rack, cabinet, power distribution unit, or cable-management accessory; it serves as the upper panel component within the applicable rack enclosure system.
