Frequently Asked Questions

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

A: These baby safety window and sliding door locks are designed to fit most standard sliding windows and sliding door tracks, including common aluminum and PVC frame styles. They work by clipping onto the frame track to limit the opening distance. If you have an unusually deep or narrow track, we recommend measuring your track width before purchasing.

A: No tools or adhesive are required. The butterfly-shaped locks are designed for quick, tool-free installation — simply clip them onto your window or door track. They can also be removed and repositioned easily, making them ideal for renters or anyone who wants a non-permanent childproofing solution.

Q: How many locks do I need for a typical home?

A: This depends on the number of windows and sliding doors in your home. The 1-pack is great for a single room or targeted use, while the 3-pack is ideal for covering multiple windows in a nursery, living room, or bedroom. Many parents choose the 3-pack to ensure consistent protection throughout the home at a better value.

Q: Are these locks safe for children — are they free from harmful chemicals?

A: Yes. According to the product specifications, these locks contain no high-concern chemicals, making them a safe choice for use in homes with infants and young children from newborn through 6 years of age.
