Silver metal storm door latches

Your Heat Seal latches are no longer available, unfortunately. This is a problem with the older style storm window hardware. They are becoming a thing of the past with the advent of vinyl insulated replacement windows. With that being said I would suggest using the 91-010 and the 91-011 latches. If you're handy, you may get them to work if you cut off the "bump" at the ends to match you latch tip. I have done this in the past for this type of latches.
