This is the Fairfield Lockset. Although we do not sell the Fairfield Lockset or parts for the Fairfield Lockset, the Normandy Lockset will fit your door. Measure from the center of your lockset to the edge of your door (your backset length) and then order the Normandy Lockset with the corresponding backset. If your lock does not look like any of the locks shown on this website then we DO NOT have parts for it.
