Sliding Door Safety Foot Lock, Adjustable Stainless Steel Patio Door Guardian for Top/Bottom Rail, Child Proof Hands-Free Security Bar for Glass & Aluminum Doors.

["🛡️ BUILT TO LAST, DESIGNED NOT TO RUST:​ Unlike traditional metal locks that rust and stain your door frame, our foot lock is crafted from high-impact ABS plastic (used in premium safety helmets). It provides reliable strength against forced entry while remaining lightweight, silent, and completely rust-proof—perfect for humid climates or rainy seasons.","🦶 HANDS-FREE CONVENIENCE:​ Install it on the bottom rail​ for easy foot operation when your hands are full (groceries, laundry). Or mount it on the top rail​ (out of children's reach) for added protection. Fits most standard patio, balcony, and glass sliding doors on the INSIDE track only.","🌬️ SECURE BREEZE MODE:​ Why choose between security and fresh air? Our unique design features two locking channels. Switch to the \"Vent\" position to keep the door slightly ajar for airflow while maintaining a secure barrier that prevents the door from opening wide enough for an intruder to enter.","👶 KEEP KIDS & PETS SAFE:​ Young children and pets are naturally curious about opening doors to the outside. This sliding door foot lock acts as a physical barrier, preventing toddlers from accidentally sliding the door open and wandering out, giving parents one less thing to worry about.","🔧 RENTER FRIENDLY & FLOOR PROTECTION:​ Set up in seconds without screws or tools. The adjustable length ensures a snug fit. Equipped with soft rubber end caps, this lock protects your flooring from scratches and provides a non-slip grip—unlike hard metal bars that can damage tiles or wooden floors."]
