Cole Sewell screen door lock

Thanks for your post! The door handle you have here looks like it could be replaced with the 40-117 Inside Latch, 40-145 Storm Door Latch, or the 40-150 Inside Handle. They each have a 1-3/4" installation hole spacing.

Carefully review and compare each of their dimensions and design on the website to determine which of these is the best option for your repairs.
