It installs in the SR-40-32 rack cabinet to prevent bypass airflow — the uncontrolled movement of warm exhaust air back into the cool-air intake path. By closing off open rack spaces, the VBK-S32 helps maintain proper thermal management in equipment cabinets. It is a sold-per-unit accessory used by rack installers, AV integrators, IT technicians, and data center infrastructure professionals when configuring or modifying rack enclosure airflow.\u003c\/p\u003e\n\u003cp\u003eThe VBK-S32 is intended for use with the MIDDLE ATLANTIC SR-40-32 rack enclosure. It fits into the standard rack opening to block venting in unused panel positions. This type of vent blocker is commonly installed during initial rack build-out or when reconfiguring equipment layouts, ensuring that cooling airflow is directed through active equipment rather than escaping through open slots.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBlocks unused vent openings in the SR-40-32 rack enclosure\u003c\/li\u003e\n  \u003cli\u003ePrevents bypass airflow that can reduce cooling efficiency\u003c\/li\u003e\n  \u003cli\u003eOEM-matched accessory for proper fit and finish in the SR-40-32 cabinet\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for flexible quantity ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the MIDDLE ATLANTIC SR-40-32 rack enclosure as a direct-fit vent blocker accessory.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by rack integrators, AV technicians, or IT infrastructure professionals. Power down or de-energize active equipment in the rack before working inside the cabinet where possible.
