Balcony Window Door Stopper

Tired of your balcony door slamming shut every time the wind picks up? This simple wedge keeps your window or door open even on breezy days.

What sets this stopper apart from the many others you'll find online is flexibility. Most stoppers are rigid, which works fine until someone forgets the stopper is there and forces the window shut, potentially damaging the frame or the window itself. This one is designed to be flexible and forgiving: if someone closes the door without noticing it, the wedge will give way rather than cause damage.

The model is intentionally soft/flexible. This is a feature, not a flaw. For the safety of your window and frame, you want something that yields under force, not something that fights back.
