Orbit 30 blocks have the best breaking load to weight ratio in the world.
The sophisticated construction has reduced the number of balls in the ball bearing, thus limiting friction.
Ball bearing, carbon fibre reinforced acetal reagent, with stainless steel shackle.
Reactor: ø 30 mm
For ropes up to: ø 8 mm
Weight: 75 g
Working load / breakage: 550 / 1100 kg
