Middle Atlantic RIB-5-GRK-36B – 5-Bay GRK Riser Base 36"D

Product Overview

The Middle Atlantic RIB-5-GRK-36B is a 5-bay riser base kit for GRK series rack systems with a 36-inch depth, designed to elevate a row of GRK racks off the floor and create a structured cable routing zone beneath the equipment. By raising the rack row, this riser base provides a dedicated pathway for power cables, low-voltage signal cables, and structured cabling runs that would otherwise compete for space within or behind the rack itself. The black finish (B designation) integrates with standard GRK rack aesthetics. This accessory is a standard infrastructure component in high-density AV and IT equipment rooms where cable management discipline is a design priority.

Product Description

In multi-bay rack installations, under-rack cable routing is one of the most effective strategies for maintaining a clean, accessible cabling infrastructure. The RIB-5-GRK-36B supports this approach by providing a rigid, load-bearing base riser that spans a 5-bay GRK row and lifts the entire rack assembly to a consistent elevation. The space created beneath the racks can be used for conduit entries, cable trays, power distribution runs, and horizontal cable management. The 36-inch depth matches the standard GRK rack depth configuration, ensuring the riser base aligns with the rack footprint without overhang or gap. The 5-bay span means a single riser base covers the full width of a standard GRK multibay row, providing a unified base structure. Construction is heavy-gauge steel with a black powder-coat finish, providing durability and a finished appearance consistent with GRK rack aesthetics. The riser integrates with GRK rack leveling and anchoring systems, and can be combined with cable management accessories available through Middle Atlantic. Available through Creation Networks at creationnetworks.net.
