Hey! Greetings from New York. I'm writing you about a 26-353 look-alike that are the typical sash pivot bars for our windows. The difference between yours and mine is that mine is about 11/16th of an inch wide, the pins themselves are offset, so that there is a "left" and "right" pin, not a mirror image and there are dimples near the lower screw holes to help with initial alignment(?) This differs so widely with the image of your part number (all other measurements are within tolerances) that I thought that I'd write first.
These are for the upper pane of a certainteed window.
Can you help? Thanks in advance, Jim
