Need pin replaced for storm window (part of a triple track)

Thanks for posting. You will need to remove the tilt corner key from the window and compare its dimensions to those we have listed on our site here. See the video below to see how you can remove your old key.

Thank you for the photos. You have older storm window parts that were manufactured by Allen Stevens. They are no longer in business. I'm not sure you will be able to find the exact match to your parts. We placed a couple of suggested parts and videos on this page for you to review. Match up the "thickness" of the leg on the corner. You also want to have a closer look at the remainder of our selection here to see if you could adapt any of our other options to be used in place of your original one.
