Place the 3-1/2 inch chrome back plate against the door surface, aligning it with the bore hole and the lockset's spindle or bolt mechanism. — Position the Back Plate
Slide the lockset's bolt or spindle through the back plate and the door's bore hole. Secure the lockset according to its specific installation instructions, using the provided screws. — Install the Lockset
