Frequently Asked Questions

Q: What types of windows and doors are these baby safety locks compatible with?

A: These butterfly-shape window and sliding door locks are designed to fit most standard sliding windows and sliding patio doors that have a track rail. They work by clipping onto the track to limit how far the window or door can slide open. We recommend measuring your track width before purchasing to confirm compatibility.

Q: Do I need tools or adhesive to install these sliding door stoppers?

A: No tools or adhesive are required. The locks are designed for simple, tool-free installation — just clip them onto the window or door track. They can be removed just as easily, making them ideal for renters or anyone who wants a non-permanent childproofing solution.

Q: How many locks should I buy for my home?

A: This depends on how many sliding windows and doors you have. The 1-pack is perfect for a single room or to try the product, while the 3-pack is a great value option for covering multiple windows or doors throughout your home. Many parents recommend securing every accessible sliding window and door for comprehensive safety.
