window venting lock

A home owner from lansing, michigan says:
I need a window ventilation lock for a Caradco double hung window (wood with vinyl clad). For security purposes, this would allow me to leave my window open but only at a certain predetermined height.

Thanks for posting! Do you have pre-existing vent latch holes already? If so, could you give me their dimensions?

If not, please look at our 26-387 Face Mount Single Action Vent Lock Kit. Do you think this may work? Make sure to see our tutorial video on how to install this kit!
