Questions & Answers (1)

Question: I have a 1978 home with all Dexter doorknobs and I want to update from bright brass to nickel. The doors are 1 3/8” thick with a backset of 2 3/8”. The hole for the doorknob is smaller than the one required for a Schlage F40 V GEO 619. Will your Dexter J40CNA619 Corona Privacy Knobset fit without having to enlarge the doorknob hole or make the latch hole deeper? Your fast service response is greatly appreciated. Thank you, Bob Griffen.

Asked by Robert Griffen on July 22, 2020

Answer: Robert, This will not work. It requires the same door prep of a 2-1/8" bore hole.
