Aituzero 8-Pack Replacement for Blum 30-310-11-02 Hinges – Concealed 110°/120° Self-Closing, Lifetime Replacement

Upgrade your cabinets with a concealed, reliable hinge solution

The Aituzero 8-pack replaces Blum 30.310-11.02 hinges with a modern, concealed design that keeps cabinet interiors clean and accessible. The self-closing action is available at 110 and 120 degrees, delivering a smooth, controlled close that enhances everyday use without sacrificing style or function.

These hinges are built for long-lasting performance. A PA plastic body combines with a dense Zamak zinc alloy to resist impact and daily wear, while a nickel-plated finish adds an extra layer of corrosion resistance. In real-world use, this combination supports quiet operation and dependable door motion through years of opening and closing.

Important compatibility notes

This hinge is a direct replacement for older Blum Compact 31 hinges, but screw hole locations differ. When replacing an old-style hinge, you may need to re-drill two small wood screw holes. The mounting plate is not included, so please verify your plate compatibility and overlay before purchasing.
