How to Install Middle Atlantic Vented Top

• Power down all equipment and follow proper safety procedures before beginning installation.
• Inspect the rack top surface to ensure it is clean, level, and free of debris that could interfere with mounting.
• Align the vented top with the upper edges of the MRK, VRK, VMRK, WR, WRK, or DRK rack, ensuring the perforated pattern faces upward to maximize airflow.
• Slide the vented top onto the rack rails and secure it using the rack’s mounting hardware or the hardware provided with the top, ensuring a snug fit without over-tightening.
• If access to cable bundles is required, remove the removable two-space service plate as needed. After completing maintenance, reinstall the service plate to maintain cable organization and top integrity.
• Verify clearance and airflow by powering on the equipment and observing that heated air rises freely through the vented surface. Confirm that no cables, cords, or components obstruct the perforations or create hotspots.

Frequently Asked Questions

• Q: Which rack families are compatible with the Middle Atlantic Vented Top? A: The vented top is designed to fit WR, WRK, MRK, VRK, VMRK, and DRK racks, providing broad compatibility within Middle Atlantic’s line of cabinets and stands.
• Q: How does the 64% open area affect cooling?
