DMM Duralock Klettersteig

Sold Out

Big and burly – our Klettersteig carabiner’s wide gate opening and wide body make it first choice in any situation where large internal volume and high strength are required.

As with our Equal D and Offset D connectors, the geometry helps keep the loading as close to the strongest part of the body as possible (i.e. along the spine). High quality materials and Hot Forging gives increased dynamics and excellent wear resistance making it particularly suitable for clipping onto safety lines or attachment points.

 The Durolock (Dual Rotor Lock) was designed to minimise the chances of accidental gate opening, and maximise levels of security. Its complex, yet easy to manipulate gate requires four distinct actions to open, and once released auto locks back to safe. It is perfect for complex/busy rigging applications.
