MEASURE YOUR WINDOWS TRACK: The window lock is designed for sliding windows, sliding doors, and vertical windows. Please measure your window track size: height must be greater than 0.48 inch ( 1.22 cm) and width must be less than 0.61 inch ( 1.55 cm) before ordering window locks. Window locks come with a vertical key, which can be used on the middle track of the window.
UPGRADED PROTECTION DESIGN: Enhanced protection design. Each window lock features two fixing holes; secure it on the window track, which significantly boosts the holding power of the lock. Use double hole locks on heavy windows/doors for added security. Window locks also include protection pads to prevent scratches or damage to your window and improve stability.
WIDE USAGE: Window locks allow you to keep windows slightly open or fully closed, reducing the risk of accidents caused by climbing through windows, preventing pets from escaping, and keeping outsiders from entering your home. Window locks can be secured in a slightly open position for ventilation. When the window is fully locked, it protects your property from damage during heavy rain and hurricanes. This sliding window lock is suitable for homes, apartments, bedrooms, offices, and more.
EASY TO INSTALL: No extra installation tools or drilling required.
