Middle Atlantic MRK-4426-AV-AB – 44SP 26D AV Rack Add-a-Bay
Product Overview
The Middle Atlantic MRK-4426-AV-AB is a 44-space, 26-inch-deep Add-a-Bay expansion unit for the MRK-4426-AV rack system, designed to extend existing MRK installations with additional rack space and matching AV-configured infrastructure. This product is intended for AV integrators and system designers who have already deployed an MRK-4426-AV base rack and need to expand capacity without replacing the primary enclosure. Common search terms include Middle Atlantic MRK Add-a-Bay expansion rack, 44SP AV rack expansion unit, and MRK-4426-AV-AB add-on bay.
Product Description
The MRK-4426-AV-AB adds a fully configured bay to an existing MRK-4426-AV installation, providing 44 rack spaces at 26 inches of interior depth in a form factor that gangs directly to the parent unit. The Add-a-Bay design means this enclosure is not a standalone rack—it requires an existing MRK-4426-AV base rack for structural support and proper installation. This approach allows system designers to scale AV rack capacity incrementally, matching the growth of AV systems over time without the cost or disruption of replacing the primary enclosure. The AV-configured pre-build includes cable management and power infrastructure consistent with the MRK-4426-AV base, maintaining a uniform installation standard across the combined bay assembly. The 26-inch depth suits the majority of professional AV equipment in commercial installation environments. The unit maintains the aesthetic and structural continuity of the MRK series when ganged with the base rack. This expansion approach is commonly specified in corporate AV build-outs, large conference room systems, and education AV deployments where phased capacity planning is practical. For configuration guidance and pricing, contact Creation Networks.
