Middle Atlantic VBK-E28 ERK Series 28-Inch Vent Blocker Kit
Overview
The Middle Atlantic VBK-E28 is a vent blocker kit designed for ERK series racks with a 28-inch depth. Blank panels and vent blockers do more than fill empty space — open rack gaps create bypass airflow paths that short-circuit front-to-rear cooling and raise equipment temperatures. Installing the VBK-E28 in unused rack sections forces air through the equipment you need cooled rather than around it, a straightforward fix for any rack running active cooling or densely loaded gear. The VBK-E28 ships in a black finish that matches standard ERK rack aesthetics.
Compatibility
The VBK-E28 is built specifically for Middle Atlantic ERK series racks with a 28-inch depth. Verify your rack depth before ordering — Middle Atlantic's ERK line spans multiple depth configurations, and vent blocker kits are depth-specific. This kit is not rated for non-ERK Middle Atlantic enclosures or third-party rack frames. If you are outfitting a full rack accessory build, confirm the ERK base series designation on your rack's label or order documentation before purchasing.
Installation Notes
Installation is a panel-fit operation — no tools beyond basic hand hardware should be required for standard ERK rail mounting. The kit weighs 1.8 lbs shipped, so handling and positioning are straightforward. Ensure the target rack units are fully cleared of cables or obstructions before seating the blocker to get a flush fit that actually seals the airflow gap.
