Hi,
I am currently in the process of attempting to refurbish my old aluminum windows. (probably norandex) and I'm guessing made around the 1970's. These pieces are black and plastic. The current ones have no markings on them. I ordered 18-142 not realizing they had 2 holes instead of one. They are also about 1/16th or so wider and get hung up when I try to put the window back into the frame. One f the sticking points seems to be the approximate 1" distance from the top to the centered hole. I have looked at your sash caps until my eyes are bloodshot (slight exaggeration) but cannot seem to find one that works.
Thank you in advance for your assistance.
Karen
