Middle Atlantic Side Panels, 40 RU, 42" D, GRK Racks

Designed to perfectly complement Middle Atlantic’s GRK rack systems, this pair of side panels is the ideal enclosure accessory for the 40 RU, 42" deep GRK frames. Specifically engineered to fit GRK-40-42LRD and GRK-40-42HLRD models, these panels deliver a clean, professional look while protecting valuable gear in busy control rooms, broadcast studios, audio installations, and IT environments. By sealing the sides of your GRK enclosure, they help maintain an orderly infrastructure, reduce dust intrusion, and enhance the overall structural integrity of your rack setup. Whether you’re outfitting a new installation or retrofitting an existing GRK rack, these side panels offer a reliable, purpose-built solution that aligns with Middle Atlantic’s reputation for rugged, industry-grade rack systems.

• Compatibility and fit: These panels are designed to precisely fit GRK-40-42LRD and GRK-40-42HLRD rack models, ensuring clean alignment with the rails, consistent gaps, and a cohesive, professional appearance across the entire enclosure.
• Size and depth coverage: With 40 rack units (40 RU) in height and a 42-inch depth, the panels deliver full side coverage that matches the frame dimensions, helping to shield equipment from dust while accommodating deep equipment footprints common in professional AV and data installations.
• Durable construction: Built to withstand daily use in demanding environments, the side panels maintain their shape and finish over time, resisting bending and surface wear so that your rack maintains a sharp, showroom-ready look even after years of service.
• Protection and organization: By enclosing the sides of the GRK rack, the panels reduce exposure to incidental contact and debris, aiding cable management and contributing to a tidy, protected interior that supports reliable equipment performance.
• Easy retrofit and maintenance: These panels are designed for straightforward installation on compatible GRK frames, enabling quick upgrades or retrofits without a full rack rebuild. When needed, removal is simple for maintenance, cleaning, or reconfiguration.

How to Install Middle Atlantic Side Panels

• Verify your GRK rack model (GRK-40-42LRD or GRK-40-42HLRD) and ensure the rack is in a stable, level position before starting installation.
• Orient the left and right side panels to match the corresponding sides of the rack frame, and confirm the panel edges align with the top and bottom rails for a flush fit.
• Attach each panel using the rack’s standard mounting holes and hardware, or use the hardware provided with the side panels if included; tighten screws gradually and evenly to avoid misalignment or binding.
• Check the alignment from multiple angles to ensure the panels sit flush against the frame with consistent gaps along the front and rear edges, and verify there is no interference with doors, panels, or cabling paths.
• Repeat the process on the opposite side if you are enclosing the entire rack, then recheck all screws to confirm a secure, uniform installation and a professional, finished appearance.
