    Step-by-Step Installation Guide for The Door Bull:

    • Step 1: Place the jamb plate on the door frame, about 18 inches above the doorknob. Ensure the cylinder on the plate faces the wall, not the door. Mark the center of the slotted hole. Install a one-inch set screw and loosely tighten the jamb plate. Note: This screw will be removed later.
    • Step 2: Close the door and slide the face plate onto the jamb plate. Adjust the jamb plate until there's a 1/16 inch gap between the face plate and the door. Drill three 1/8 inch pilot holes at the back of the jamb plate. Install and tighten the 3-inch screws.
    • Step 3: Enhance strength and balance by replacing one screw from each hinge on the opposite side of the door with the additional 3-inch screws provided.
    • Step 4: Decide where to store the face plate holder and position it on the wall. Drill two 1/8 inch pilot holes at the back of the holder. Install and tighten the 1-inch screws.
