Replace missing sliding screen door latch and pull

Looking at your photo I see you have something like our 86-023 turn lock. I also notice looking your Patio screen door (and the impression of the old handles) that it seems that it's been installed backwards. The 83-018 handle goes on the inside of the door so that the 86-023 lock turns into the open space in the handle. The outside handle, our 83-019, is just a straight pull. You need to take the screen door from the track and turn it around to reinstall it the correct way. You will have holes on both end side rails of the door. Andersen usually gives you a cover plate to cover up the screw holes on the non locking side.
