how to install Middle Atlantic Split Solid Rear Door for 45 RU WMRK Racks with Knockout

• Before you begin, verify that your enclosure is a standard 19-inch, 45 RU WMRK rack and that you have the appropriate mounting hardware for your specific model.
• Power down equipment and remove any rear access components or doors that may interfere with the installation.
• Position the split solid rear door so the hinge side aligns with the rack’s rear frame. The design is intended to integrate with the rack’s existing mounting points and hardware.
• Secure the door to the rack using the appropriate screws or bolts specified by the rack manufacturer. Ensure the door sits flush and that the hinge operates smoothly without binding or interference from cables or equipment behind the door.
• Prepare for the locking solution by using the 25mm x 150mm knockout opening. Install your customer-supplied electronic lock or compatible locking hardware according to the manufacturer’s instructions, ensuring clear access and reliable engagement.
• If you plan to use a separate handle model, attach the handle to the door per the handle’s installation requirements, ensuring full engagement with the locking mechanism and unobstructed door operation.
• Test the door: verify that it closes securely, latches properly, and that the electronic lock (once installed) enables smooth, secure access. Confirm that cables do not impede door operation and that ventilation and airflow are not obstructed.
