If you have one of the older Corbin 100, 110 or 120 door closers, you will have to replace it with a Corbin Russwin DC3210 for interior doors, or the Corbin Russwin DC6210 for exterior doors. Both the DC3210 and DC6210 will match the hole spacing of the Corbin 100, 110 or 120 door closers, so you will not have to redrill holes. Your current door closer is probably marked SL72, Clarksdale, MS.
