Latch replacement

I have seen your storm door latch many times. This is a very old and discontinued part, and to my knowledge it hasn't been made in years.

I would say the best replacement option we sell is our 40-150. This should install the same way without issue and will even take the spindle from the exterior handle. However it's not quite as tall as your original. With that in mind you may need to shim it up a little so that it can meet the keeper.
