                      Yes I have one. I used it to help repair a steel door that burglars had broken the deadbolt lock off of and damaged the door. My door had two lock holes one for the deadbolt and other for door knob and only the deadbolt area was damaged. I had to trim off some of the bottom to clear the door knob assembly but I wanted as much coverage as possible for the deadbolt and that was this unit. This is thinner than I expected [perhaps less than 1/32"] but best I found and perhaps thin to fit in a tight door jamb fit. Used this to strengthen the lock area and hide the burglar damage, also went with a much stronger Schleigh deadbolt. I do recall determining the correct part was difficult because there were severial similar units and the sizes were listed differently from model to model of the same brand and think I recall some listed the thickness as "adjustable" which I do not see how that can be done on a one piece unit. Measure twice buy once.

                          Keep in mind that this is wider than some older doors hence you will have a little gap, i split the gap between both side so it is not too bad and made it work.
