I just moved into a place that has two keys for the deadbolt and entry. I want to replace them with a single keyed entry set. The deadbolt is 2
3/4" backset, but the other lock is backset 7". It has a Schlage 4 3/4" extension link.The only thing I have found to fit it is a Schlage Series A (which is what the bottom lock currently is, the top is an ACE hardware deadbolt). These are out of my price range, but I cannot find any other residential lock set that has this 7" backset.
Does anyone know if another manufacturer produced an extension link for their latch (the Schlage link will not work with locks other than the Series A) or has a 7" latch? thanks
