We have a triple pane, double hung window that has a broken clip on the top window.
The clip is 2 1/4 inches long with two threaded holes about 1 inch apart and an outside clip that is about 1/4 inch with a collar. the collar goes on the outside of the window frame and the two threaded holes go on the inside of the window. We have searched hardware and local window people and no one has seen these.
