I have a thermal guard window item #478A. Product No. 424461. These windows were installed 10/8/79. Do you have a replacement part?..I need two for the same window. Thank you, Liz

I tried to cross reference those Thermal Gard part numbers but I did not find anything. Can you post a quick picture and description of the Thermal Gard part you are replacing?

Hi, I have three pictures of the window lock that I had inquired about. the first two are of the broken one, the last is what they should look like . If you have them great. Thanks
