Im trying to find the right sized part to fit in these vinyl sashes. I've attached photos showing the empty one inch space and another from a window that still has one in it.

I'm afraid we don't have this kind of vent lock in that size. Could you instead use something like our 26-106 or 26-107? I'm just not sure if the width will be the same.
