BILLROAD Child Safety Door Top Lock - Adjustable Metal Door Top Locks (4 Pack)

Safe, Simple, and Flexible Door Safety

Designed to rest on top of the door like a saddle, the BILLROAD Child Safety Door Top Lock keeps safety within reach without getting in the way. Its metal construction and thoughtful design make unsupervised door access less likely, while still allowing quick entry when you need it.

The lock is adjustable for door thicknesses from 0.8 to 2.2 inches, which means it can fit many standard interior and exterior doors. For doors that open inward, installation details note you may need to mount on the exterior portion of the frame. The result is a slim, dependable top lock that stays mostly hidden from view.

Double-sided operation means you and others can open or close from either side, reducing the chances of accidentally locking yourself out. When you don’t need the lock, you can slide it aside instead of removing it completely, preserving convenience.

• Easy, one-screw installation: secure the lock with a single fastener and set it to lock or unlock by sliding.
• Sturdy painted metal stands up to daily use and resists rust and water intrusion, helping it last for years.
• Fits most doors in homes with kids or pets—bathrooms, bedrooms, basements, and more—thanks to adjustable thickness.

What you get with the 4-pack is value and flexibility: safety across multiple doors without cluttered hardware. Each lock rests on top, out of the way and easy to reach for adults, while staying just out of little hands' reach.

Installation tips: measure door thickness first, position the lock on the door top, drill the included screw into the frame, and test the slide mechanism. For inward-swinging exterior doors, install on the exterior frame for best results. Regular checks ensure the lock stays aligned and functions smoothly.

Built for everyday life

From morning routines to evening visits, a top-door lock helps maintain boundaries in busy homes. While not a guarantee of any safety outcome, many households view this as a practical piece of a broader safety routine.
