4. Installation Instructions
The Probrico DLS07 door knob is designed for easy installation with basic tools. Follow these steps for a successful setup:
- Prepare the Door: Ensure your door has standard bore holes and is between 1-1/4 inch and 1-3/4 inch thick.
- Adjust the Latch: The steel adjustable latch can be set to either 2-3/8 inch (60mm) or 2-3/4 inch (70mm) backset. Adjust as needed for your door.
- Install the Latch: Insert the latch into the door edge hole and secure it with the provided screws. Ensure the latch bolt faces the door frame.
- Install the Exterior Knob: Place the exterior knob assembly through the door, aligning the spindle with the latch mechanism.

6. Maintenance
To ensure the longevity and smooth operation of your Probrico DLS07 door knob, follow these simple maintenance guidelines:
- Cleaning: Wipe the knobs regularly with a soft, damp cloth to remove dust and fingerprints. Avoid abrasive cleaners or harsh chemicals, as these can damage the brushed nickel finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the latch mechanism and the interior moving parts to maintain smooth operation. Do not use oil-based lubricants, as they can attract dust and debris.
- Tightening: Check the mounting screws periodically and tighten them if necessary to prevent wobbling or looseness.
7. Troubleshooting
If you encounter any issues with your Probrico DLS07 door knob, refer to the following troubleshooting tips:
- Knob is Loose: Tighten the mounting screws located on the interior rosette. If the screws are stripped, they may need to be replaced.
- Latch Does Not Retract Smoothly: Ensure the latch is properly aligned with the strike plate. Lubricate the latch mechanism with a silicone-based lubricant. Check for any obstructions in the door frame or latch bore.
- Door Does Not Latch Properly: Verify that the strike plate is correctly aligned with the latch bolt. Adjust the strike plate position if needed. Ensure the door frame is not warped.
- Lock Mechanism Jams: If the lock mechanism becomes difficult to operate, apply a small amount of silicone lubricant to the thumb turn and the emergency release slot. Ensure no debris is obstructing the mechanism. If the issue persists, the internal mechanism may be damaged and require replacement.
- Emergency Release Not Working: Ensure you are using an appropriate tool (coin or flathead screwdriver) and applying sufficient, steady pressure to turn the mechanism in the emergency release slot.
