- Prepare the Door: This latch is designed for out-swinging wood or metal doors between 3/4 inch and 1-1/8 inches thick. Verify your door thickness.
- Check Hole Spacing: The latch is compatible with 1-1/2 inch, 1-3/4 inch, or 3 inch hole spacing. If replacing an old latch, use the existing holes if they match. If installing on a new door, mark and drill holes according to the template provided with the physical product (not included in this digital manual).
- Determine Backset: Ensure your door has a 7/8 inch backset from the door jamb for proper latch operation.
- Install Latch Mechanism: Position the main latch mechanism on the door, aligning it with the pre-drilled holes. Secure it using the provided screws.
- Attach Knob: Connect the tulip knob to the latch mechanism, ensuring it operates smoothly. Secure the knob with its respective screws.
- Install Strike Plate: Position the strike plate on the door frame so that the latch bolt engages properly when the door is closed. Mark and drill pilot holes, then secure the strike plate with screws.
- Test Operation: Close the door and test the latch operation. Ensure the knob turns freely and the latch bolt retracts and extends smoothly. Make any necessary adjustments to the strike plate for optimal performance.
4. Operation
The Wright Products Universal Knob Door Latch operates simply:
- To open the door from the outside, turn the tulip knob to retract the latch bolt, then pull the door open.
- To open the door from the inside, turn the interior handle (if applicable) or knob to retract the latch bolt, then push the door open.
- To close the door, simply push it shut. The latch bolt will automatically engage with the strike plate, securing the door.

5. Care and Maintenance
To ensure the longevity and smooth operation of your door latch, follow these simple maintenance tips:
- Cleaning: Wipe the latch periodically with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Lubrication: If the latch mechanism feels stiff, apply a small amount of silicone-based lubricant to the moving parts. Do not use oil-based lubricants, as they can attract dirt.
- Tighten Screws: Periodically check all mounting screws and tighten them if they have become loose. Loose screws can affect the latch's performance and durability.
- Inspect for Wear: Regularly inspect the latch for any signs of wear or damage. If any components appear worn or broken, consider replacing the unit to maintain security and functionality.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Latch does not retract smoothly. | Dirt or debris in mechanism; lack of lubrication; misaligned components. | Clean the mechanism. Apply silicone lubricant. Check alignment of internal parts and adjust if possible. |
| Door does not latch securely. | Strike plate misalignment; loose mounting screws; worn latch bolt. | Adjust the strike plate position. Tighten all mounting screws. If the latch bolt is worn, replacement may be necessary. |
| Knob is loose or wobbly. | Loose set screw or internal fastening. | Locate and tighten the set screw on the knob. If the issue persists, inspect internal connections. |
