Storm window latch corner

Thanks for writing! Please start by taking a look at our 91-191 Corner Latch Set. We do not have the cover that your existing latch has but I do believe this should be the replacement you need.

To confirm, carefully compare the dimensions shown on the diagram below. Be sure to take a look at our video tutorial below for an idea on how to install the hardware, should you need assistance.
