Middle Atlantic RIB-3-WMRK-36 3 Bay Riser Base 36 in

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND RIB-3-WMRK-36 is a 3-bay riser base designed for rack system installations requiring a 36-inch depth configuration. This component provides a stable, elevated foundation for rack enclosures, allowing technicians to position equipment bays at an accessible working height within structured wiring and AV rack environments. Sold individually, it is intended for use in professional rack infrastructure builds where consistent bay alignment and a secure base footprint are required. Installation is typically performed by AV integrators, IT infrastructure technicians, or low-voltage contractors.

This riser base is suited for commercial and residential structured wiring installations where Middle Atlantic Watermark-series rack systems are deployed. The 36-inch depth accommodates deeper rack enclosures common in equipment rooms, server closets, and AV equipment bays. It supports multi-bay rack configurations, making it appropriate for larger installations requiring three side-by-side rack sections to be mounted on a unified riser platform.

Key Features

• 3-bay configuration supports three adjacent rack enclosure sections on a single base
• 36-inch depth accommodates deep rack enclosures used in AV and IT environments
• Designed for Watermark-series rack systems for consistent fitment and alignment
• Sold as an individual unit for precise quantity ordering on multi-bay projects

Compatibility

Designed as an OEM-style riser base for Middle Atlantic Watermark-series 3-bay rack enclosure installations with a 36-inch depth profile.

Installation Notes

Installation is typically performed by low-voltage or AV integration technicians during the rack build phase, before equipment is loaded into the enclosures. Ensure the floor surface is level and capable of supporting the combined load of the riser base and all mounted equipment. Power down and disconnect all rack-mounted electronics before repositioning or modifying the riser base assembly. Follow local building codes and manufacturer assembly guidelines for anchoring and stabilization.
