- Arc Rosette plates (2, one for each side of the door)
- Latch mechanism
- Privacy spindle
- Privacy pin
- Strike plate
- Mounting screws
3. Installation Instructions
This door set is designed for easy installation on standard interior doors. A 2-3/4" backset is included. Ensure your door is prepared with the appropriate bore holes for the latch and knob assembly.
- Prepare the Door: Ensure the door has a standard 2-1/8 inch cross bore and a 1-inch edge bore. The backset (distance from the door edge to the center of the cross bore) should be 2-3/4 inches.
- Install the Latch Mechanism: Insert the latch mechanism into the edge bore of the door. Secure it with the provided screws, ensuring the latch bolt faces the door frame.
- Install the Exterior Knob Assembly: Place the exterior knob assembly (knob and rosette plate) through the cross bore, ensuring the spindle aligns with the latch mechanism.
- Install the Interior Knob Assembly: Align the interior knob assembly with the exterior assembly, ensuring the privacy spindle engages correctly.
- Secure the Assemblies: Use the provided mounting screws to firmly attach both knob assemblies to the door. Tighten screws evenly to prevent misalignment.
- Install the Strike Plate: On the door frame, align and install the strike plate where the latch bolt will engage. Secure with screws.
- Test Operation: Close the door and test the latching and privacy functions to ensure smooth operation.
For detailed visual guidance, refer to the installation diagram provided with your product packaging.
4. Operating the Privacy Function
The Grandeur Hardware 852900 features a privacy function, ideal for bedrooms and bathrooms. This mechanism allows the door to be locked from the inside without a key.
- To Lock: From the interior side of the door, locate the small privacy pin or button on the rosette plate. Push or turn this pin to engage the lock.
- To Unlock: From the interior, simply turn the knob to disengage the lock.
- Emergency Unlock (Exterior): In case of emergency, the privacy lock can be disengaged from the exterior side using a small tool (such as a paperclip or the provided emergency key) inserted into the small hole on the exterior rosette plate.
5. Care and Maintenance
To maintain the polished nickel finish and ensure the longevity of your Grandeur Hardware door set, follow these care instructions:
- Cleaning: Wipe surfaces regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishing compounds, as these can damage the finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the latch mechanism and spindle to ensure smooth operation. Do not use oil-based lubricants, which can attract dust.
- Inspection: Periodically check all screws and connections to ensure they remain tight. Tighten any loose screws to prevent wobbling or misalignment.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob is loose or wobbly. | Mounting screws are loose. | Tighten the mounting screws on both sides of the door. |
| Latch does not retract smoothly. | Dirt buildup or lack of lubrication in the latch mechanism. | Clean the latch mechanism and apply a silicone-based lubricant. |
| Privacy lock does not engage/disengage. | Privacy pin/spindle misalignment or obstruction. | Check for obstructions. Ensure the privacy spindle is correctly seated during installation. If issues persist, re-install the interior knob assembly. |
