These sliding door locks are seriously a parent's best friend when you've got curious little ones running around. The 6-pack gives you plenty to secure all your sliding glass doors, windows, and even closet doors throughout the house. Made from strong ABS plastic that's BPA-free and non-toxic, they're safe for homes with kids and pets. Installation couldn't be easier - no tools or drilling required thanks to the pre-applied double-sided adhesive. Just clean your surface, peel off the backing, and stick it on. They work on glass, wood, plastic, pretty much any smooth surface. The design is low-profile so they blend in rather than looking like obvious child-proofing gear. What's great is how effective they are - they prevent doors from opening more than a couple inches, enough to stop kids from getting into off-limit areas or accidentally wandering outside. They're also useful for pet owners trying to keep animals out of certain rooms. The white color is neutral and unobtrusive, and the quality feels substantial enough to last through years of use. If you're baby-proofing your home or just want some extra security for sliding doors, these locks deliver serious protection without any permanent modifications to your home.
