MeKo Carabiner Hooks

This month’s featured component is a little different — and still packed with engineering.

Our custom-designed carabiner hook was part of our holiday mailings. At first glance, it’s a small give-away. But behind it lies a clear mechanical challenge; to create a carabiner from a single sheet of metal, with no hinges, that opens easily with the thumb yet remains form-stable over time.

The hook is laser-cut from spring steel and draws inspiration from a well-known component in the MedTech world: hypotubes. Early prototypes showed just how critical the slit geometry in such designs is. To avoid local stress peaks, the final design splits the load: the main spring action comes from an open ring at the base, while the slit pattern supports the final opening motion.

The result is a compliant mechanism that shows what’s possible when material expertise, smart design and cross-functional collaboration come together.

And that’s exactly how we approach every project. We love a technical challenge, transfer insights across applications, and grow our knowledge with every part we manufacture. The more demanding the component, the more rewarding the process.
