A home owner from VA BEACH VA says:
The backset (width for bracket on inside of door) is on 1.5 inches, will this product work?

Thanks for posting! By back set, do you mean the face of the door where the lock is being installed? For storm doors I have worked on, the face of the door is normally 2" wide, while you have only a 1-1/2" face. Looking at the 40-028 In-Swinging Door Handle lock's dimensions (see below), you will need 7/8" from the edge of the door to the center of the lock. Since the lock face width is 7/8", I'm figuring you should have 1/4" on the back edge of the lock. There would be no room for error here.
