Keep your home safe for the whole family with this handy safety window lock! It stops windows from opening too wide, keeping kids out of danger, while still letting in fresh air through a 7cm/2.8" gap. It’s also great for holding windows open securely, even on windy days. Made with tough 3M VHB tape, it’s built to last—tested to handle up to 30kg (66lbs) of pull and 27kg (60lbs) of push. Want to open the window fully? Just push and pull two buttons at the same time—a tricky task for little hands. Installation is quick and drill-free: stick it on with the included tape and you’re done! Need to remove it? Heat it with a hairdryer and use dental floss to lift it off, leaving no marks behind. Perfect for both temporary and permanent setups!
