Concealed hinges are a staple in modern door design, but not all deliver the strength, adjustability, and sleek look that today’s homes and commercial spaces demand. As SMED—established in 2003, ISO 9000 certified, and a leading door spring hinge factory in China—we engineered the C167 to solve common pain points of standard concealed hinges. This hinge blends heavy-duty performance with 3D adjustability, making it ideal for both residential and commercial flush doors. In this article, I’ll break down why the C167 stands out, and how our factory’s expertise ensures its reliability.

C167: Lightweight & Automatic Return for Effortless Operation

The C167 combines robust performance with user-friendly features, crafted from lightweight aluminum alloy for exceptional corrosion resistance and reliable operation in humid indoor or outdoor settings. With two hinges installed, it supports doors up to 45 kg (99 lbs)—making it well-suited for standard interior doors, cabinet doors, and lighter commercial applications. The hinge also includes an adjustable closing force and automatic return function, allowing for smooth, self-closing action that enhances convenience and safety. Lightweight, automatic return hinges (C167) offer reliable door operation for up to 45kg, ideal for interior and commercial applications.

Easy Installation & Adjustable Closing Power

Designed for straightforward surface-mounted installation, the C167 eliminates the need for complex recessing. Its adjustable closing force lets users customize the speed and power of the door’s return, which is ideal for spaces where controlled movement is preferred—such as offices, schools, or residential cabinetry. The hinge operates quietly and supports up to 200,000 working cycles, ensuring long-term durability without sagging or noise.

Versatile Compatibility for Multiple Door Types

Compatible with wood, steel, and aluminum frames, the C167 accommodates door panels from 36 mm (1.417 in) in thickness and offers a 180° opening angle for full accessibility. Its aluminum construction provides a balance of strength and weight savings, making it a practical choice for both contractors and homeowners looking for reliable, low-maintenance hardware. The C167 hardware supports diverse door types and thicknesses, offering 180° rotation and durable, lightweight aluminum construction for contractors and homeowners.

Conclusion

The C167 isn’t just a hinge—it’s a product of SMED’s expertise as a door spring hinge factory. We combine heavy-duty strength, 3D adjustability, and versatility to meet modern design needs, backed by ISO 9000 quality standards and personalized support.
