Installation Instructions
Before you begin, ensure your door is between 3/4" and 1-1/8" thick. The installation requires drilling three 1/2" holes with universal spacing to fit 1-3/4", 1-1/2", and 3" hole patterns.
Tools Required:
- Drill
- 1/2" Drill Bit
- Screwdriver (Phillips head recommended)
- Measuring Tape or Ruler
- Pencil
Step-by-Step Installation:
- Prepare the Door: Mark the locations for three 1/2" holes on your storm or screen door. Ensure the spacing matches one of the universal patterns (1-3/4", 1-1/2", or 3") for the knob assembly.
- Drill Holes: Carefully drill the three 1/2" holes through the door at the marked locations.
- Install Knob Assembly: Insert the exterior keyed knob and the interior lever assembly through the drilled holes. Ensure the spindle aligns correctly between both parts.
- Secure the Assembly: Use the provided screws to fasten the interior and exterior components together. Tighten securely, but do not overtighten to avoid damaging the door or the lock mechanism.
- Install Strike Plate: Position the strike plate on the door frame, aligning it with the latch bolt when the door is closed. Mark the screw holes and the outline of the latch.
- Mount Strike Plate: Drill pilot holes for the strike plate screws if necessary, then attach the strike plate to the door frame using the provided screws.
- Test Operation: Close the door and test the latching mechanism. Ensure the knob turns smoothly and the latch engages properly with the strike plate. Test the key operation from the exterior.
Operating Instructions
Locking the Door:
- From the exterior, insert the key into the cylinder and turn it to engage the lock. Remove the key.
- From the interior, the knob can be locked by turning the small lever or button (if present) on the interior side, or by turning the knob itself to a locked position before closing the door. The positive locking system allows you to set the lock and then close the door, which will then be secured.
Unlocking the Door:
- From the exterior, insert the key into the cylinder and turn it to disengage the lock. The knob will then turn freely.
- From the interior, turn the knob or lever to release the latch.
Maintenance
To ensure the long-term performance and appearance of your Wright VK670 knob, follow these maintenance guidelines:
- Cleaning: Clean the knob and lever surfaces periodically with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: If the key mechanism or latch bolt becomes stiff, apply a small amount of graphite lubricant or a silicone-based spray lubricant specifically designed for locks. Do not use oil-based lubricants, as they can attract dirt and dust.
- Tightening: Periodically check all mounting screws and tighten them if they have become loose. Do not overtighten.
- Inspection: Inspect the knob and latch for any signs of wear or damage. If any components are damaged, consider replacing the unit to maintain security and functionality.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob is stiff or hard to turn. | Lack of lubrication; dirt or debris in mechanism. | Apply graphite or silicone-based lubricant to the keyway and latch mechanism. Clean any visible debris. |
| Key does not turn or is difficult to insert. | Key is bent or damaged; debris in keyway; incorrect key. | Ensure you are using the correct, undamaged key. Apply graphite lubricant to the keyway. If the key is bent, replace it. |
| Latch does not engage with strike plate. | Strike plate misalignment; door sag. | Adjust the position of the strike plate on the door frame. Check door hinges for sag and tighten if necessary. |
| Knob assembly feels loose. | Mounting screws are loose. | Tighten the mounting screws on the interior side of the knob assembly. Do not overtighten. |
