Lightweight Kilogram for kilogram of working load BB Orbit Blocks are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement.

This gives minimum friction across the full working load range. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. Simple, versatile and secure attachment The single block is easily lashed to an attachment point, and can also accept Dyneema Links and shackles for a variety of efficient attachment alternatives. The Dyneema Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema Link can also be removed and replaced by a shackle, custom lashing or strop. These blocks are far more compatible with Dyneema\/Spectra lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles. Low profile and compact The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation. The flexible Dyneema Link used in multi-sheave blocks provides 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post.

Lightweight Kilogram for kilogram of working load BB Orbit Blocks are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement.

This gives minimum friction across the full working load range. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. Simple, versatile and secure attachment The single block is easily lashed to an attachment point, and can also accept Dyneema Links and shackles for a variety of efficient attachment alternatives. The Dyneema Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema Link can also be removed and replaced by a shackle, custom lashing or strop. These blocks are far more compatible with Dyneema\/Spectra lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles. Low profile and compact The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation.
