About This
- Measuring Window Track Dimensions: Before purchasing, please carefully verify the width of your window track to ensure the product fits properly and functions correctly. The height must be greater than 0.48 inches, and the track width must be less than 0.39 inches (if the track width is greater than 0.39 inches but less than 0.61 inches, please use thin plastic shims).
- Durable and Practical: Crafted from sturdy aluminum alloy with exquisite craftsmanship, this window safety lock is rust-resistant, Anti-aging, and resistant to deformation, ensuring long-lasting durability. The lock comes with two types of protective pads—rubber pads and thin plastic pads—which effectively prevent scratches on the window frame while enhancing grip during locking, thereby improving stability and security.
- Wide Range of Applications: Our sliding window safety locks are widely used in a variety of settings, including homes, apartments, hotels, and offices. Window locks allow you to freely control whether sliding windows are fully closed or slightly open for ventilation. This not only effectively reduces the risk of accidents but also prevents outsiders from opening the windows to gain access to your home, providing you with comprehensive safety protection.
- Easy Installation: No additional tools or drilling are required. Simply select the appropriate protective spacer based on the width of your window track, then tighten the two built-in screws to complete the installation. The window lock can be easily adjusted for reuse or reinstallation, allowing for either a full closure or a limited opening for ventilation. Heavy-duty doors and windows can be secured with multiple locks simultaneously to enhance stability and security. (Depending on the space available in the window track, you can use either an Allen wrench or a vertical key to complete the installation.)
- Value Bundle: This set includes 4 window locks, 4 hex wrenches, 1 vertical key, 4 rubber protective washers, and 4 thin plastic protective washers. If you encounter any issues during installation or use, please contact us and we will assist you.

SMART HOME FAQ
Yes — many modern devices support multiple platforms.
Matter-certified devices can work across Alexa, Google Home, and Apple HomeKit at the same time.
Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
Most homeowners start with:
Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
Smart thermostats and smart plugs help reduce wasted energy by automating heating, cooling, and power usage.
It depends on your ecosystem.
