The window slider stops on my single hung Milgard windows are fragile and easily break. I have not been able to identify the part on the web.

Hello! I believe our 26-122 vent lock will work for your Milgard window. Please just compare the outside dimensions (3/8" x 2") to your hardware. The interior housing will look different, but it may still work. If they don't match, let me know how they differ.
