Adjustable Sliding Window Lock Stopper & Child Safety Security Lock

Keep your home secure while preventing dangerous window falls with a heavy-duty adjustable sliding window lock stopper. Our adjustable sliding window lock and anti-theft safety stopper clamps firmly onto sliding window and door tracks to restrict how far they can open. Designed to safeguard children and pets from accidental falls, this security lock allows you to keep windows partially open for fresh air circulation while preventing unauthorized intrusion from the outside. Engineered with an adjustable rotary key mechanism, it tightens securely over window track frames without requiring power tools, drilling, or permanent modifications. The inner clamping jaw is lined with a protective rubber friction pad that grips track metal tightly while preventing scratches, scuffs, and frame damage. Crafted from high-tensile, corrosion-resistant alloy metal, this compact safety lock withstands heavy push force. Upgrade your home security with a no-drill sliding window track stopper and patio door lock built for family safety.
