Setup (Installation)
This double dummy set is designed for easy installation on modern pre-drilled doors and is also suitable for restoration projects. It provides a complete set for both sides of one door.
- Prepare the Door: Ensure your door is clean and free of debris. For new installations, ensure the door is pre-drilled with standard bore holes.
- Attach Dummy Spindles: Insert the dummy spindles through the door's bore hole. These spindles do not engage a latch mechanism but provide a mounting point for the knobs.
- Position Plates: Place one Craftsman plate on the interior surface of the door and the other on the exterior surface, aligning them with the dummy spindles and screw holes.
- Secure Plates: Attach the long plates to both the interior and exterior surfaces of the door using the provided mounting screws. Ensure the plates are level and securely fastened. Do not overtighten.
- Install Knobs: Slide the Waldorf door knobs onto the dummy spindles. Secure each knob by tightening the set screw located on the knob's shank with the provided hex key.
- Final Check: Gently pull and push the knobs to ensure they are firmly attached and do not wobble.

Operating
The Nostalgic Warehouse Craftsman Double Dummy Door Knob is designed for doors that only require a push or pull function. It does not contain a latching or locking mechanism. To open or close the door, simply push or pull the door using the knob as a handle.
Maintenance
To maintain the finish and functionality of your door knob:
- Cleaning: Clean regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishing agents, as these can damage the satin nickel finish and crystal knob.
- Inspection: Periodically check all mounting screws and set screws for tightness. Tighten if necessary to prevent wobbling or loosening.
- Crystal Care: For the Waldorf black crystal knob, use a mild glass cleaner on a soft cloth if needed, then wipe dry immediately.
Troubleshooting
Most issues with a double dummy knob are related to installation.
- Knob is Loose: If the door knob feels loose, check the set screw on the knob's shank. Use the hex key to tighten it securely. Also, ensure the mounting screws holding the plates to the door are tight.
- Plate is Loose: If the decorative plate is loose, tighten the mounting screws that secure it to the door.
- Knob Does Not Turn: This is a double dummy knob, designed not to turn or engage a latch. Its function is purely as a fixed handle for pushing and pulling the door.
