Product Overview

The Middle Atlantic RIB-3-GRK-36B is a 3-bay riser base designed for use with Middle Atlantic GRK series racks at 36-inch depth. Riser bases elevate rack systems to an ergonomic working height and provide a stable foundation for multi-bay rack configurations, while also creating underfloor cable routing access in applicable installations.

Product Description

The RIB-3-GRK-36B integrates directly with GRK series rack frames and accommodates the full 36-inch depth profile. In a 3-bay configuration, it provides a continuous riser platform that keeps all rack bays at consistent elevation and alignment. The riser base also provides the structural footprint for securing multi-bay GRK systems to the floor, which is a key requirement in seismic zone installations and high-traffic facilities management environments.
