Middle Atlantic GRK-RR-S40 – 40SP 10-32 Split Rackrail, 4-Piece
Product Overview
The Middle Atlantic GRK-RR-S40 is a 40-space (40U) split rackrail set with 10-32 threaded mounting holes, designed to add an extra mounting plane inside GRK Series broadcast racks. The split, 4-piece configuration makes the rails easier to handle and position during installation in a fully loaded rack. A 44-space version, the GRK-RR-S44, is also available on this listing for taller GRK enclosures.
Product Description
GRK Series racks are deep broadcast and AV enclosures, and many builds need more mounting positions than the factory rails provide. Adding a GRK split rackrail set creates an additional plane for rear-mount equipment support, cable management hardware, and accessories without modifying the rack itself. The GRK-RR-S40 spans 40 rack spaces and uses 10-32 threaded holes, the threading standard most common in broadcast and professional AV racks, so existing rack screws and hardware carry over. The split rail design divides the full rail height into sections — four pieces per set — which simplifies maneuvering rails into a rack that already has equipment installed and allows sections to be positioned where mounting support is actually needed. This extra rack rail set fits GRK Series racks specifically; it is not a universal rail kit. Choose the GRK-RR-S40 for 40-space GRK racks or the GRK-RR-S44 variant for 44-space frames. Both versions are stocked alongside GRK rack accessories, bus bars, and thermal management hardware at Creation Networks.
