55 BB Orbit Double Link Head Block
Less friction, ultimate performance
Ball Bearing Orbit Blocks boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema rope link head. Their precision allows the optimum number of ball bearings in loaded areas and eliminates them in active areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arms and beckets.
Lightweight – Kilogram for kilogram of working load, these are the worlds lightest.
Highest working load in its class – The orbital ball-bearing arrangement gives the largest possible bearing race diameter to maximise load performance.
Simple and secure attachment – The Dyneema Link is easily fitted and is retained by a moulded retainer clip.
Low profile and compact – The flexible Dyneema Link provides controlled rotation of 0 – 90 degree orientation and connects directly to the head of the block rather than an intermediate headpost, reducing weight and giving a low profile with full articulation.
