Keep curious kids and pets safe with these brilliant sliding door locks that require NO tools or drilling! The clever triangular design provides strong support while being virtually invisible once installed. Made from durable ABS rubber with extra TPR soft rubber on contact areas to prevent scratches on your doors and windows. Installation takes seconds - just clean the surface, peel off the 3M tape backing, stick it in place (make sure it's somewhere little hands can't reach), and hold for about 24 hours for maximum adhesion. To lock, simply pull the latch up 90 degrees; push it down to unlock. Important notes: you need at least 7mm clearance between door/window gaps for these to work properly, and for best security, use at least two locks per door or window. These versatile locks work on sliding doors, windows, patios, closets, showers, and wardrobes - basically any smooth surface including glass, wood, plastic, and metal. The white color blends seamlessly with most home decor without standing out. When it's time to remove them (maybe the kids grew up or you're moving), just use a hairdryer and dental floss - they come off clean without damaging your surfaces. Seriously, if you've been worrying about little ones accessing off-limit areas or pets getting where they shouldn't, these locks provide peace of mind without the hassle of permanent installation. They're the kind of simple, effective safety solution every family with young children or curious pets should have!
