Middle Atlantic PROMRK-RR – Extra Cage Nut Rackrail for MRK/VRK
Product Overview
The Middle Atlantic PROMRK-RR series adds an extra pair of heavy-gauge, cage nut style rackrails to MRK and VRK series enclosures. A second set of rails creates additional mounting planes for four-point equipment support, rear-mount accessories, or split-depth layouts inside deep racks. Each pair ships with mounting hardware and is available in 24, 37, 40, and 44 rack unit heights to match the enclosure being outfitted.
Product Description
Deep MRK and VRK racks frequently need more than the standard front and rear rail sets: heavy servers and amplifiers call for four-point mounting, and rear-facing panels, power strips, and cable management all compete for rail real estate. The PROMRK-RR series answers with additional rackrail in heavy-gauge steel using square cage nut openings, which let installers place hardware of various thread types exactly where it is needed and replace worn nuts without retapping. Rails are sold in pairs and include the mounting hardware required to secure them in the rack. Four heights cover the common MRK and VRK enclosure sizes, from 24 RU up to full-height 44 RU. The cage nut format distinguishes this series from pre-tapped 10-32 rail offerings, making it the right choice for mixed-hardware installations and IT equipment that ships with cage nut kits. Select the variant that matches your rack height from the table below, and pair the rails with Middle Atlantic shelves, lacer bars, and panels available at Creation Networks.
