Philips storm window latch

Thanks for reaching out to us. It's tough to make out the exact design of your latch while it's still in the window. There are a few important details that are still obscured. For now you can consider our 91-033P or 91-050, but keep in mind that neither is going to be exact. You will ultimately need to remove the original and carefully compare both the design and dimensions to the photos and measurements we show for each respective product. That will allow you to confirm if one of these will work.

Another thing to keep in mind is that there's a good chance we simply don't have anything that can replace this. Storm windows in general have been dying off for decades and replacement parts are getting harder and harder to get a hold of. That's just the reality of the industry right now, unfortunately. Just something to keep in mind as you move forward on this project.
