The Schlage 40-251 Tri-Option Deadlatch is designed for easy and simple installation as a replacement springlatch for interior doors. It is compatible with both 2-3/8 inch and 2-3/4 inch backsets.

1. Prepare the Door: Ensure the door preparation is clean and free of debris.

3. Insert Deadlatch: Insert the deadlatch into the bore hole on the edge of the door, ensuring the latch bolt faces the correct direction for door closure.
4. Secure Faceplate: Attach the selected faceplate to the deadlatch and secure it to the door edge using the provided mounting screws. Ensure the screws are tightened firmly but do not overtighten.

For detailed visual instructions, refer to the product overview video in Section 1.

4. Operating Instructions

The deadlatch mechanism allows the door to be securely closed and latched. When the door is closed, the spring-loaded latch bolt extends into the strike plate, holding the door shut. To open, the door handle or knob (not included) retracts the latch bolt, allowing the door to swing open.

5. Maintenance

To ensure the longevity and smooth operation of your Schlage 40-251 Tri-Option Deadlatch, follow these maintenance guidelines:

• Regular Inspection: Periodically inspect the deadlatch for any signs of wear, damage, or loose screws.
• Cleaning: Keep the latch mechanism and faceplate clean and free of dust, dirt, or debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners.
• Lubrication: Annually, apply a small amount of silicone-based lubricant to the moving parts of the latch bolt to ensure smooth retraction and extension. Do not use oil-based lubricants as they can attract dirt.

6. Troubleshooting

If you encounter issues with your deadlatch, consider the following common problems and solutions:

• Latch Not Retracting: If the latch bolt does not retract properly when the handle is turned, check for any obstructions in the door frame or strike plate. Inspect the internal mechanism for damage, such as a broken anti-shim pin, which can prevent proper retraction.
• Door Not Latching Securely: Ensure the strike plate on the door frame is correctly aligned with the latch bolt. Adjust the strike plate if necessary. Check if the latch bolt is fully extending.
• Loose Components: Tighten any loose mounting screws on the faceplate or the door knob/handle assembly.

If problems persist after attempting these solutions, it may indicate internal component failure, and replacement of the deadlatch may be necessary.
