Replacement door latch

This appears to be the old Sears brand storm door striker. We did carry this at one time but it was discontinued around 2017. 

We have alternative replacement options for the handle set, but not necessarily for this striker. In order to get something else to work you would need to replace everything, handle and all. My recommendation is our 40-117 kit, which includes its own strikes for both the deadbolt and latch.
