Steinwhale 3Pack Home Security Door Reinforcement Lock, Childproof Safety Door Lock Latch Inside Stopper, Add High Security to Prevent Home Unauthorized Entry, Aluminum Construction Finish Black

Brand: Steinwhale

Color: Black

Features:

• CNC Machined Aviation Aluminum: Unlike cheap die-cast locks on the market that are fragile and have rough surfaces, our lock is crafted from a solid block of aviation-grade aluminum using precise CNC machining. This ensures zero structural weak points and allows for a flawless, premium sandblasted anodized finish that will never rust, fade, or easily scratch.
• Ultimate Home Security & Anti-Theft: Withstands up to 800 lbs of force to prevent doors from being kicked in. This heavy-duty Steinwhale door reinforcement lock provides 12 times the strength of a standard deadbolt. It adds critical extra security to your home, effectively defending your family and property against intruders.
• Childproof & Toddler Safety: Keep your little ones safe. If your primary goal is toddler safety, simply install this lock higher on the door frame out of their reach. The unique spring-loaded design requires a precise pinch-and-pull motion that is extremely difficult for young children, effectively preventing them from wandering outside or opening the door to strangers.
• Quick Access & Inside Night Defender: While extremely difficult for toddlers, it is highly user-friendly for adults. Simply pinch the lock from the top and bottom and pull it towards you to unlock it from the inside in seconds. It provides absolute peace of mind at night and ensures a quick and easy escape during emergencies.
• For Inward Swinging Doors ONLY: Specifically designed exclusively for inward swinging doors. Please verify your door type before purchasing. This heavy-duty security door latch is strictly NOT compatible with outward swinging doors, sliding doors, double doors, screen doors, or french doors. To ensure the door closes smoothly, a minimum gap of 0.2' (5mm) is required between the door and the frame for the mounting plate.
• Installation Requires Drilling: Comes with 7pcs of high-quality extended screw and requires a power drill for a sturdy, permanent installation directly onto the door frame. Because permanent drilling into the structural frame is necessary to achieve the 800 lbs impact resistance, this is NOT a damage-free setup and is not recommended for renters seeking adhesive or tool-free solutions.
