Features:

Kilogram for kilogram of working load, Orbit Blocks™ are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle, full-length fasteners, and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.

The flexible Dyneema® Link provides controlled rotation and 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height.

Automatic and Manual ratchet in one block
Up to 20:1 holding power
Easily fitted and securely retained Dyneema® Link head
Smooth easing of sheets
High performance cleating

Dinghy mainsheet systems
