This is for camper windows that have the bar that slides out and props them open. It should slide out the hole and lock into place. This will hold the window fully open and also prevent the bar from being bumped and sliding back in. This will be useful in the master bedroom where the window is by the head of the bed and gets bumped frequently where the bar then slides in and almost impales those sleeping.

File "_p" has supports, while the other is without supports.
