Steinwhale 3Pack Door Reinforcement Lock Home Security, Childproof Safety

Steinwhale 3Pack Door Reinforcement Lock Home Security, Childproof Safety

• Upgraded Screw Structure, No More Broken Rivets: Standard door reinforcement locks rely on cheap rivets that inevitably loosen, fall out, and render the lock useless after long-term use. We’ve upgraded to a premium, fully adjustable screw mechanism. This allows you to easily retighten the lock for lasting stability. More importantly, it provides a crucial fail-safe: in the rare event of an internal spring jam, you can quickly dismantle the lock with a standard screwdriver, completely avoiding costly damage to your door or frame.
• Ultimate Home Security & Anti-Theft: Withstands up to 800 lbs of force to prevent doors from being kicked in. Unlike other die-cast locks 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 premium sandblasted anodized finish that will never rust, fade, or easily scratch. This heavy-duty door reinforcement lock provides 12 times the strength of a standard deadbolt, adding critical extra physical security to your home to effectively defend 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.
• Strictly 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, or french doors. To ensure the door closes smoothly, a minimum gap of 0.2" (5mm) is required between the door and the frame.
• Installation Requires Drilling: Comes with high-quality extended screws 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 800lbs impact resistance, this is NOT a damage-free setup and is not recommended for renters seeking adhesive or tool-free solutions.
