Anti-Slam Window Stopper Wedge

Keep the breeze flowing and the windows safe.

Enjoy fresh air in your home without the constant worry of doors and windows slamming shut. Our perfectly angled Anti-Slam Window Stopper Wedge is the ultimate, drill-free solution to keep your windows securely open, exactly how you want them.

Designed to fit snugly between the window sash and the frame, this blocker prevents sudden closures caused by strong drafts or wind gusts. Whether you are airing out the kitchen, letting in a gentle summer breeze, or simply keeping the room ventilated, this tool ensures your window stays put while protecting the glass and hinges from damage.

Key Features & Benefits:

• Wind & Draft Resistant: Effectively blocks the window from slamming shut or blowing wide open during sudden weather changes.
• Universal Wedge Design: The sloped, geometric shape allows it to fit easily into different gap sizes, making it ideal for most standard, tilt-and-turn, and casement windows.
• Damage-Free Installation: No screws, adhesives, or drilling required. Simply slide the wedge into the gap, and remove it just as easily when you want to close the window.
• Safe & Durable: Made from tough, non-scratch material that provides a firm grip without damaging your window frames, sills, or paintwork.
• Child & Pet Friendly: Helps prevent accidents involving trapped fingers or paws by keeping heavy windows securely locked in an open position.

How to use: Simply open your window to the desired angle and wedge the stopper between the bottom (or side) of the window frame and the sill. Press gently to ensure a secure fit.
