I have some old aluminum windows, the glides or slides are no longer available for purchase, so I designed these from the last good set I have.

They are the same for the top and bottom of the window, and they go in all 4 corners.

My windows slide well again.

Tolerances are tight.

They would probably slide better with nylon, but I don't have any at the moment.
