Overview: The Fuliko 3" Stop metal door reinforcement lock adds a powerful layer of protection to your home. Engineered to withstand 800 lbs of force — roughly 12 times the strength of a typical deadbolt — this flip-style lock is built to prevent unauthorized entry while remaining easy to use. Reinforced Design: This upgraded model uses a 5-hole reinforcement plate (versus the common 4-hole design) for improved stability and longer-lasting resistance against forced entry. Quick Installation: Install the security lock in under 5 minutes with a power screwdriver and drill. It is made for inward-opening doors and comes with a full installation guide. Our support team is available if you have any setup questions. Everyday Use: Operation is simple and tool-free. Place your index finger on the top and your thumb beneath the unit, flip the lock toward the hinges, then pull outward. Daily locking and unlocking is fast, and the mechanism still allows quick exit in emergencies. Childproof Safety: The spring-loaded action prevents children from opening the door to strangers, providing extra peace of mind when you’re away. It also offers added security for seniors and women living alone. Durability & Compatibility: Constructed from premium materials for long-term reliability, the lock complements a variety of interior styles. It is compatible with multiple door types, including wood and metal, making it a versatile security upgrade for any residence.
