Installation Instructions
This deadbolt is designed for easy installation and includes all necessary mounting hardware. Ensure your door thickness is between 1.375 inches and 1.75 inches and that the backset is either 2.375 inches or 2.75 inches.
Tools Required:
- Phillips Head Screwdriver
- Measuring Tape
- Pencil
- Drill (if creating new holes)
- Wood Chisel (if needed for mortise)
Step-by-Step Installation:
- Prepare the Door: If installing on a new door, mark and drill holes for the deadbolt according to the provided template (if included). For existing installations, ensure the holes are clean and correctly sized.
- Install the Latch Bolt: Insert the latch bolt into the edge bore hole. Ensure the latch bolt is oriented correctly for your door's swing. The latch is adjustable for 2.375-inch or 2.75-inch backsets; adjust as needed before securing. Secure with screws.
- Install the Exterior Cylinder: Place the exterior cylinder assembly through the cross bore hole on the outside of the door. Ensure the tailpiece passes through the latch bolt mechanism.
- Install the Interior Thumb Turn Assembly: Position the interior thumb turn assembly on the inside of the door, aligning the mounting posts with the holes in the exterior cylinder. Ensure the tailpiece engages with the thumb turn mechanism.
- Secure the Assemblies: Fasten the interior and exterior assemblies together using the provided mounting screws. Tighten screws evenly to prevent binding.
- Install the Strike Plate: Mark and chisel out a mortise for the strike plate on the door frame, aligning it with the latch bolt. Secure the strike plate with screws.
- Test Operation: Close the door and test the deadbolt operation with both the key from the exterior and the thumb turn from the interior. Ensure smooth locking and unlocking.

Maintenance
Regular maintenance ensures the longevity and smooth operation of your deadbolt.
- Cleaning: Clean the exterior finish with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the oil rubbed bronze finish.
- Lubrication: Periodically apply a small amount of graphite lubricant or a silicone-based spray lubricant into the keyway and the latch mechanism. Do not use oil-based lubricants as they can attract dirt and dust.
- Tighten Screws: Check and tighten all mounting screws periodically to ensure the deadbolt remains securely fastened to the door.
