Middle Atlantic Vent Block Kit ERK/DWR 20in. Deep - VBK-E20

Middle Atlantic VBK-E20 Vent Block Kit for ERK/DWR 20-Inch Deep Racks

Overview

The Middle Atlantic VBK-E20 is a vent blocker kit designed for Middle Atlantic ERK and DWR series racks built to 20-inch depth. Blank and vent panels leave gaps in rack airflow management that allow hot exhaust air to recirculate back to equipment intakes — a common cause of thermal throttling and premature component failure in densely loaded AV and security equipment racks. The VBK-E20 seals those openings, forcing conditioned air through the correct front-to-back path rather than bypassing your equipment. If you're building out a rack enclosure with mixed equipment heights and hitting thermal issues, this is the targeted fix before you upsize the cooling system.

Compatibility

The VBK-E20 is engineered specifically for Middle Atlantic's ERK (Elite Rack) and DWR (Deskwall Rack) enclosure families at 20-inch depth. Confirm your rack's listed depth is 20 inches (50.8 cm) before ordering — Middle Atlantic offers vent block kits in multiple depth configurations, and a mismatched depth kit will not seat correctly. This kit is not a universal fit; it is dimensioned for the ERK and DWR internal panel geometry. If you are running a different Middle Atlantic series or a non-20-inch depth variant, verify the correct VBK model against your enclosure's spec sheet. Finish is black, matching standard ERK/DWR interior panels.

Installation Notes

Ships at 2.2 lbs — lightweight enough that no structural reinforcement of the rack frame is required for installation. No tools or fastener torque specifications are published in the available evidence; follow the installation guidance included with the kit and Middle Atlantic's standard panel-mounting procedure for your enclosure series.
