We need to replace block and tackle channel balances (more on that later) and some pivot shoes.
I would like a shoe that allows the window not just to tilt, as we have now, but also to allow us to lift the window out. As they are, we have to unscrew the pivot bar, slide it over and out of the cam to remove the window. And - oops - when we do, the shoe slams up into the balance. Live and learn.
Dims on this shoe with toothed cam are: 9/16 thick x 1 and 1/4 wide and 2" H
Outside Dims on this grooved pivot bar 3" x 9/32 x 3/16"
Not sure if 15-152, 15-129 or this 15-178 will do what we need.
Many thanks.
Jean
