Middle Atlantic L5-MK-33-SN Millwork Kit
Overview
The Middle Atlantic L5-MK-33-SN is a millwork integration kit designed for installing Middle Atlantic rack systems into custom cabinetry, furniture enclosures, and architectural millwork — the type of deployment where exposed rack rails are not acceptable and the AV or security infrastructure must disappear behind finished woodwork. The L5-MK-33-SN addresses the mechanical gap between a standard equipment rack and the surrounding cabinet structure, providing the hardware needed to secure the rack assembly cleanly within a built-in enclosure without field fabrication. If you are specifying a rack for a boardroom credenza, reception desk, or in-wall security head-end cabinet, this kit is the component that bridges the rack to the millwork surround.
Compatibility
The L5-MK-33-SN is part of Middle Atlantic's L5 millwork series. Verify compatibility against your specific Middle Atlantic rack enclosure model and cabinet rough-opening dimensions before ordering — millwork kits are dimension-specific and will not transfer between rack width or depth configurations. Consult the Middle Atlantic millwork product line documentation to confirm the L5 series fits your rack unit count and enclosure depth. For broader AV rack enclosure planning, cross-reference your rack's external dimensions against the cabinet opening spec.
Installation Notes
Millwork kit installations require accurate rough-opening preparation in the cabinet prior to rack insertion. The L5-MK-33-SN is intended for finish carpentry environments — verify that the cabinet structure can support the static load of the populated rack before mounting. Review Middle Atlantic's millwork installation documentation for fastener specifications and ventilation clearance requirements, as enclosed cabinetry installations are the primary thermal risk for rack-mounted equipment. Pair with appropriate rack ventilation accessories to manage heat buildup in sealed enclosures. For power distribution inside the millwork enclosure, rack PDU options from the same product family maintain dimensional consistency within the cabinet footprint.
