3Pack Door Reinforcement Lock Home Security, Childproof Safety | Top Door Lock Latch for Toddlers Safety, Inside Defender Prevents Unauthorized Entry on Inward Doors, Withstands 800lbs

CNC Machined Aviation Aluminum: Unlike inexpensive die-cast locks available that are brittle and feature coarse surfaces, this lock is manufactured from a solid piece of aviation-grade aluminum using accurate CNC machining. Ultimate Home
Security & Anti-Theft: Resists up to 800 lbs of force to stop doors from being kicked open. This robust door reinforcement lock offers 12 times the strength of a conventional deadbolt. It provides essential additional security for your home, efficiently protecting your family and belongings from intruders.
Childproof & Toddler Safety: Ensure your young children are secure. If your main objective is toddler safety, just mount this lock higher on the door frame beyond their access. The distinctive spring-loaded mechanism needs an exact pinch-and-pull action that is very challenging for small children, successfully stopping them from wandering outdoors or opening the door to strangers. Quick Access & Inside Night Defender: While very challenging for toddlers, it is exceptionally convenient for adults. Simply squeeze the lock from the top and bottom and pull it toward you to release it from the inside in moments.
For Inward Swinging Doors ONLY: Specifically engineered solely for inward swinging doors. Please confirm your door type before buying. 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 needed between the door and the frame for the mounting plate.
Installation Requires Drilling: Includes 7 pieces of premium extended screws and needs a power drill for a solid, fixed installation directly onto the door frame. Since permanent drilling into the structural frame is required to attain the 800 lbs impact resistance, this is NOT a non-damaging setup and is not advised for renters looking for adhesive or tool-free solutions
