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.
The Boa Durolock from DMM was designed to reduce the possibility of accidental gate opening. The auto-locking gate requires four separate movements to open. This gate sequence is easily memorized and requires no extra thought for the climber. The Durolock gate is perfect for life-support or loads that require extra security.
