Hi, Barry. I agree that the 26-122 looks close. It will stay in the "in" position, thankfully. All vent latches like this do. If yours doesn't then it's probably just worn down or defective. As for whether it will work in a Harvey window, that's not something I can answer, unfortunately. These are generic parts used in many, many different brand windows. Comparing physical attributes is the only way to be sure. |
