Middle Atlantic Slim 5/AX-S Rackshelf Mounts to Front and Rear Rail - SH-5A

Middle Atlantic SH-5A Zero-Space Rack Shelf for Slim 5, AXS, SRSR, and WR Racks

Overview

The Middle Atlantic SH-5A is a zero-rack-space shelf designed for integrators who need to mount non-rack-mount equipment inside a rack enclosure without sacrificing a single rack unit. The SH-5A side-mounts to the front and rear rails of compatible Middle Atlantic racks, suspending the shelf from four anchor points and leaving the full vertical rail space available for rack-mount gear above and below. The 18.5 in W x 18.6 in D usable surface handles anything from NVRs and UPS units to networking equipment that won't take a standard rack ear, and the 250 lb weight capacity means you're not compromising on what you can set on it. Powder-coat black finish and ventilation cut-outs address both aesthetics and thermal management — heat-generating equipment won't be cooking against a solid steel surface.

Compatibility

The SH-5A is engineered for the following Middle Atlantic rack series: Slim 5, AXS, SRSR, and WR. All four series share the rail geometry that the SH-5A's 4-point side-mount system requires. The shelf accepts equipment up to 19 in nominal mounting width with 18.5 in of usable width and 18.6 in of usable depth — verify your equipment footprint against those dimensions before ordering, particularly for larger NVR chassis or battery backup units. This shelf is not a universal fit; it will not seat correctly in racks outside the listed families. If you're building out a larger system, pair this with compatible network video recorders or UPS units that lack rack ears.

Installation Notes

The SH-5A uses a 4-point side-mount configuration, anchoring to both front and rear rails simultaneously — this is what enables the zero-rack-space design and delivers the 250 lb load rating. Confirm your rack has both front and rear rails at the intended mounting location; single-post or mid-mount-only configurations are not compatible. Total shelf depth is 20 in; account for cable management and rear-rail clearance when planning depth inside shallower rack enclosures. The vented surface aids passive airflow — orient heavier, heat-producing equipment so exhaust vents are not obstructed by the shelf deck above.
