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. Wings up = locked, flat = slides freely. Install it high on the door frame, above toddler reach, to limit how far doors or windows can open. Adults operate it easily with one hand – even while holding a coffee or a baby. No auto-lock – you lock it manually each time (won’t spring shut accidentally). For best adhesion: clean surface, press firmly, then wait 48–72 hours before use. During this time, keep the area dry – moisture can weaken the bond
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 non‑toxic ABS and clear strong acrylic adhesive – the smooth finish won’t scratch frames. Adults unlock it easily, but the snug latch confuse toddler fingers and pet paws. For high‑traffic or windy doors, use both locks side by side – they handle sudden pushes or wind gusts together. Use on clean, smooth surfaces only (glass, wood, PVC). Low‑profile design blends into frames. (Indoor use only. Once stuck, can not be repositioned – test placement first before removing backing.)
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
