Oversized, yet still ergonomic and user-friendly, the Boa is ideally suited to applications where large connector volume and gate clearance are required. The large HMS shape allows for easy rotation of Italian hitches in tension rigging applications and the smooth curved internal form makes rotating the carabiner through attachment eyes simple.

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.

Anti roll out Durolock (Patented) locking mechanism gives extra security when used in close proximity with moving ropes
