Heavy Duty Anti Sag Door Hinge and Security Chain Lock Set

Sagging doors that drag against the floor are highly frustrating, and weak entry locks leave your property vulnerable to forced break-ins. This heavy-duty 2-in-1 security hardware combo features a reinforced, anti-sag galvanized steel hinge paired with a high-tensile security door chain, allowing you to easily fix misaligned doors while instantly upgrading your home or office anti-theft protection.

• Restricted Entry Security Chain: Engineered with a heavy-duty steel chain and thick mounting plates that limit door opening clearance, letting you safely identify visitors while blocking forced entry.

• Corrosion-Resistant Zinc Plating: Finished with a premium rust-proof color zinc coating that effectively resists moisture, rain, and outdoor wear, preventing bending and warping in damp environments.

• Pre-Drilled Easy DIY Installation: Features precisely placed, pre-drilled holes and includes all necessary mounting screws, allowing fast setup on both wood and metal frames with basic hand tools.
