What this hinge does Ball bearing door hinge designed for mounting on home doors, cabinet doors, windows, cabinets, tool boxes and similar applications. Bearings reduce friction so even heavier doors move more easily and consistently. Key benefits (why you need it) Smoother operation: lubricated ball bearings allow the door to open and close with minimal resistance. Quieter use: lubrication and bearings minimize noise during operation — no squeaks or rattles. Longer life: bearings reduce wear on hinge components, prolonging functional life. Corrosion protection: antirust surface treatment improves anticorrosion performance and maintains strength and appearance over time. Features and performance Ball bearing mechanism for reduced friction and consistent movement. Lubricated bearing assembly to prevent noise and ensure smooth action. Antirust-treated surface for enhanced corrosion resistance, firmness and durability. Suitable for a wide range of residential and light commercial mounting points.
