How to install Middle Atlantic Split Vented Rear Door

• Prepare the rack area: ensure the rack is unpowered and the installation space is clear of obstructions to allow room for the rear door’s removal and reattachment.
• Align the door with the rack frame: position the split rear door so the perforated sections align with the rear ventilation pathway and mounting points on the 42 RU WMRK rack.
• Attach the door: secure the door to the rack using the designated mounting points and hardware provided by Middle Atlantic for your WMRK enclosure, tightening hardware evenly to prevent misalignment.
• Install your handle (if desired): since the door ships without a handle, insert your preferred electronic handle through the 25mm x 150mm knockout opening and secure it according to the handle manufacturer’s instructions for a clean, secure fit.
• Verify operation and airflow: once installed, gently test the door’s movement and ensure the perforations remain unobstructed. Confirm that cables are routed cleanly to preserve the vented design and that the door closes securely without interference.
• Final checks: inspect the fit against the rack’s rear frame, confirm that all electrical equipment within the enclosure maintains adequate clearance, and ensure that any mounted handles do not impede airflow or door operation.
