I have 15 double hung windows with screens. The screens are held in place by 2 nylon pins at the top (5/32" x 7/8") with a collar of 1/4" in diameter about 1/4" from one of the ends. In addition, each screen has two spring loaded plunger latches, one on each side (part number
70-009 on your website).
Since the parts are nylon, they become brittle and break; in addition, the window washers lose them. I would like to replace the top pins with aluminum parts if you have them. I cannot find either aluminum or nylon replacements on your website. Can you help me? Please answer either way.
