Middle Atlantic DWR-RR46 46U Rack Rail Pair for DWR/EWR Wallrack
Overview
The DWR-RR46 is a replacement or supplemental 46-space rack rail pair designed specifically for Middle Atlantic Middle Atlantic wallrack enclosures in the DWR and EWR series. If you're adding a second set of rails to an existing wallrack for front-and-rear equipment mounting, or replacing a damaged rail in a deployed enclosure, this pair provides the exact 10-32 threaded rail pattern and 80.5-inch (204.5 cm) usable height that matches the original factory configuration. Seismic-rated construction means these are appropriate for installations in California Title 24 or IBC seismic compliance environments — a relevant spec for wall-mounted AV and security equipment racks in commercial buildings.
Compatibility
These rails are compatible exclusively with Middle Atlantic wallrack enclosures in the DWR (Slide-Out Wallrack) and EWR series at the 46U depth. The 10-32 threaded rail pattern accepts standard rack accessories including cage nuts, clip nuts, and any 19-inch EIA-310-compliant equipment — NVRs, patch panels, PoE switches, and access control panels all mount without adapters. Do not attempt to fit these rails into non-DWR/EWR enclosures; the mounting slot geometry and depth (20 inches) are specific to this enclosure family. If your enclosure is a different RU count within the same series, verify the matching RR SKU — the 46U designation is specific to this model.
Installation Notes
Each pair ships with Ecoated steel finish — a corrosion-resistant zinc electrocoat process suited for indoor commercial environments. Shipping weight is 13 lbs for the pair. Rails mount into the existing DWR or EWR enclosure side channels; no additional drilling or fabrication is required when replacing OEM rails. Confirm your enclosure depth matches the 20-inch rail depth before ordering — shallow-depth DWR variants use a shorter rail.
