Middle Atlantic FM-66SMK-2J-CHG Rack Sliding Shelf Mount Kit
Overview
The FM-66SMK-2J-CHG is a Middle Atlantic sliding shelf mount kit designed for dual 66-series rack frame installations finished in charcoal gray. This hardware kit provides the mechanical interface needed to integrate sliding shelf assemblies into compatible Middle Atlantic rack systems, keeping equipment accessible without pulling it fully out of the frame — a practical requirement in dense AV and security head-end closets where cable management and service access compete for space. The FM-66SMK-2J-CHG designation indicates a two-post junction configuration for 66-inch-deep installed frames.
Compatibility
This kit is engineered for Middle Atlantic 66-series rack frames in dual-rack configurations. It is specifically matched to the INSTD (installed/in-wall) frame depth class. If you are working with a different frame depth — such as the standard 24-inch or 31-inch Middle Atlantic open-frame series — verify the frame suffix before ordering, as sliding hardware is depth- and rail-spacing-specific. For broader rack accessories and mounting hardware compatibility across Middle Atlantic product lines, confirm your frame series and rail spacing against Middle Atlantic's frame selector documentation. The charcoal gray (CHG) finish matches standard Middle Atlantic rack frame color options; verify finish codes on adjacent hardware if color consistency across the installation matters.
Installation Notes
Mount kits of this class attach to the inner rails of the rack frame and require access to both sides of the frame during installation. Confirm rail spacing and frame depth before beginning — mismatched depth hardware will not seat flush and can compromise load ratings. Use appropriate fasteners for the rail material; Middle Atlantic frames use standard rack hardware (10-32 or 12-24 depending on frame generation). Refer to Middle Atlantic's installation documentation for torque specifications and slide extension load ratings applicable to this frame series. For complete rack enclosure planning, pair this kit with the correct shelf and frame components from the same 66-series family.
