Key Features

• -Measure your sliding door gap first. This lock fits 0.27 to 1.22 inches only. Not sure how to measure? We can help you check compatibility before you buy. Just grab a ruler for a quick check – once confirmed, you can install with confidence knowing it will lock securely and slide freely when unlocked. Perfect for sliding glass doors or balcony doors. Getting the right fit means no hassle, no wasted time, and no return shipping. Many mismatched returns happen simply because the gap wasn’t checked
• -Peel, stick, and lock – no drill, no screws. The wing design is simple: wings up = locked, flat = slides freely. Install it high on the door frame, above toddler reach, to limit how far sliding doors or windows can open. Adults operate it easily with one hand – even while holding a coffee or a baby. No keys to lose, no complex setup. For the first 48 hours after sticking, avoid touching or sliding against it to let the clear acrylic adhesive fully bond – then it’s ready for daily use
• -Works on sliding glass patio doors, closet doors, windows, shower doors, and even RVs or camper vans. Also great for home offices, laundry rooms, pantries, garage entry door, and French door. While you’re on a work call or helping kids with homework, this lock prevents toddlers or pets from wandering into off-limit areas. Perfect for parents of crawlers, pet owners, renters, grandparents, and even caregivers for adults – anywhere you need a quick, removable safety solution without drilling holes
• -Made from strong ABS and clear acrylic adhesive – smooth finish won’t scratch your frames. Adults can unlock it easily, but the snug latch is designed to confuse toddler fingers and pet paws. For frequently used doors, use both locks from the pack side by side – they handle sudden pushes or strong wind gusts better together. You can double the holding force on a busy patio door or use them on two separate windows. For best hold, use on clean, smooth surfaces only. Perfect for busy families
• -Keep fresh air flowing while blocking escapes. Leave your sliding door or window open a few inches – this lock stops kids and pets from slipping out, yet doesn’t block ventilation. Ideal for busy parents in the kitchen, remote workers on calls, or anyone with a climber toddler or curious puppy. When you move or no longer need it, remove cleanly with a hairdryer – no sticky residue left behind. Also a thoughtful, affordable gift for new parents, grandparents, or friends with a new puppy
