Adjustable Aluminum Alloy Sliding Window Safety Lock Childproof Door Security Stopper

Protect your family, childproof open windows, and prevent forced entry with this Adjustable Aluminum Alloy Sliding Window Safety Lock. Forged from high-strength, heavy-duty aluminum alloy with a wear-resistant finish, this rugged security clamp resists tampering, forceful impacts, and daily track friction without bending or stripping. It clamps directly onto the bottom or top track of horizontal sliding windows and patio doors, allowing you to lock windows completely shut or anchor them securely in a partially open position for fresh-air ventilation. Outfitted with a protective non-slip rubber friction gasket, it creates a tight, vice-like grip that will not scratch or mar window frames. Installation is quick, completely tool-free, and requires zero drilling—simply place the stopper on the track, turn the rotary key mechanism, and lock your entryway securely.

Key Features

• Heavy-Duty Aluminum Alloy Build: Solid metal construction withstands forced entry attempts, weather exposure, and regular sliding friction.

• Childproof & Pet Safety Defense: Prevents curious toddlers, young children, and indoor pets from opening high or ground-floor windows.

• Secure Fresh Air Ventilation: Locks windows partially ajar to let cool breezes circulate while keeping the opening too narrow for intruders or falls.

• Protective Non-Slip Rubber Gasket: High-friction rubber pad grips aluminum, vinyl, and wood tracks tightly without scuffing or damaging finishes.

• Tool-Free Rotary Key Tightening: Hand-tightened or key-assisted screw mechanism locks and releases smoothly in seconds without power tools or drills.

• Wide Sliding Track Compatibility: Adjusts effortlessly across standard sliding sash windows, vertical hung windows, and heavy sliding patio doors.
