Fuliko 3" Stop Metal Door Reinforcement Flip Lock — 800 lbs High-Security, 5-Hole Reinforced, Childproof for Inward-Opening Doors

Overview: The Fuliko 3" Stop Metal Security Door Reinforcement Lock is a flip-style interior lock built to withstand up to 800 lbs of force — about 12 times the resistance of a typical deadbolt. This upgraded model uses a 5-hole reinforcement plate (improved over the common 4-hole design) for greater stability and tamper resistance. Installation: Designed for inward-opening doors, the lock installs quickly — typically in under 5 minutes using a power screwdriver and drill. A detailed instruction guide is included, and Fuliko’s support team is available if you need help during setup. Operation: Everyday use requires no tools. To engage or release the lock, place your index finger on the top and your thumb beneath, push the latch toward the hinges and pull outward. The mechanism is smooth for fast access while still preventing forced entry. Childproof & Safety Features: The spring-loaded mechanism adds a childproof barrier that helps stop young children from opening the door to strangers. It also provides an extra layer of security when you’re away and can be especially reassuring for seniors and women home alone. Construction & Compatibility: Made from durable, high-quality materials, the door reinforcement lock is built for long-term use and pairs well with a variety of interior styles. It’s compatible with both wood and metal door types, offering a flexible security upgrade for most residences.
