Middle Atlantic Riser Base, 4 Bay, 38" Depth for BGR Racks

Engineered for professional AV and data-center environments, the Middle Atlantic Riser Base is a practical, time-saving solution for rough-in rack installations. The 4-bay base with 38" depth provides a stable foundation for equipment while freeing up valuable front-face space by allowing cables to pass underneath. Its 2-1/2" high profile aligns with standard rack heights, facilitating clean cable management from the start of a project. Built with heavy-duty welded construction and finished in black powder coat, this riser base resists daily wear and delivers reliable service in busy rack rooms. Ideal for four-bay BGR rack configurations, the riser base simplifies installation workflows, reduces field errors, and improves airflow and organization in any data- or AV-intensive environment.

• Time-saving rough-in design: This riser base streamlines cabling workflows by letting installers route and organize cables beneath the rack, reducing on-site labor and helping crews stay on schedule for complex projects.
• Optimal base height for clean cable paths: At 2-1/2" high, the base delivers a consistent platform that supports neat under-base cable management while ensuring compatibility with standard rack components and accessories.
• Generous depth for versatile equipment: With a 38" depth, the base accommodates a wide range of devices and power distribution options, maintaining alignment with four-bay BGR racks for stable mounting and service access.
• Durable construction and finish: Heavy-duty welded steel paired with a black powder coat finish provides lasting durability, resistance to wear in busy rack rooms, and a professional aesthetic for visible installations.
• Four-bay compatibility for organized systems: Specifically designed for BGR rack configurations, this base supports multiple components in a single footprint, enabling efficient organization of switches, patch panels, and other equipment.

how to install Middle Atlantic Riser Base

• Prepare the installation area: ensure the rack frame sits on a level surface and that you have clear access to the four-bay footprint where the riser base will be placed.
• Align the riser base with the rack footprint, matching the four-bay layout to the rack posts or mounting points as specified for your BGR configuration.
• Place the base under or between the rack rails and secure it using the manufacturer-recommended hardware or factory-supplied fasteners to ensure a stable foundation.
• Route cables through the base’s pass-through area before mounting top-mounted equipment, giving you clean under-base cabling paths and room for future additions.
• Install equipment on top of the base in the usual order, then secure devices as required by your rack standard. Check clearance between devices and the base to prevent contact and ensure proper ventilation.
• Verify the setup: check for levelness, stability, and smooth cable routing underneath. Power up a test load to confirm that the cabling remains organized and that airflow is unobstructed.
