Middle Atlantic PROWMRK-ZRA – Z-Rail Adapter for WMRK Racks
Product Overview
The Middle Atlantic PROWMRK-ZRA is a cage nut Z-Rail adapter that converts standard rackrail to “Z” style on WMRK Series racks. The Z-style profile supports side-mounted applications, giving integrators a clean way to mount accessories and hardware along the sides of the rack. Adapters are sold in pairs and are available in 24 RU (PROWMRK-ZRA-24) and 45 RU (PROWMRK-ZRA-45) heights to match common WMRK rack configurations. It is a straightforward rack rail upgrade for commercial AV, IT, and network equipment installations built on the WMRK platform.
Product Description
WMRK Series racks ship with standard rackrail, but some equipment layouts call for side-mounted hardware that standard rail geometry does not accommodate. The PROWMRK-ZRA solves this by adapting the existing rail to a Z-style profile, opening up side mounting positions without replacing the rack or its rail. Because the adapters use cage nut construction, installers retain the flexible, repeatable hardware attachment that cage nut rackrail provides during integration and later equipment changes. Each part number covers a full rail height: specify the PROWMRK-ZRA-24 for 24-space WMRK racks or the PROWMRK-ZRA-45 for 45-space configurations. Adapters are sold in pairs, so one part number outfits both rail positions for a side-mount application. For integrators standardizing on Middle Atlantic enclosures, this adapter keeps side-mount provisions consistent across deployments such as equipment rooms, data closets, and rack-based AV systems.
