This product is a patented metal buckle under the CLIPON AK501 series. It features a streamlined exterior configuration with a compact structural design and refined industrial aesthetics. Technically, the buckle innovatively incorporates high-strength POM engineering plastic as the elastic component, thereby replacing the conventional metal spring structure. This design effectively mitigates metal fatigue while significantly enhancing durability and service life. Testing results demonstrate that the buckle is capable of enduring more than 10,000 opening and closing cycles without structural failure, indicating superior safety performance and operational stability. The product is suitable for high-end pet harnesses, outdoor equipment, and various strap system applications, achieving an integration of functional performance and aesthetic value.
