BRAKING SYSTEM EFFICIENCY
To assist braking, only a type H or HMS safety carabiner should be used. With a type B carabiner, the "brake assist" function will not work properly.
We recommend using the Simond Goliath screwgate carabiner, Secure & BLC. (Model code 8608353).
For the same reason, do not use this belay system with a rope diameter < 8.9 mm or the "brake assistance" function will not work properly.
