Ronstan Series 30 Orbit Single Lashing Head with Nylatron Sheave - Becket Option

Ronstan 30mm plain bearing Orbit block is to be used with wire or rope in high load applications. Ideal where a wire kicker, wire halyard or similar is used. With lashing head and the option to add the Ronstan wide dee shackle (RORF1850S-2) in either orientation to create a conventional loop top block. The block also has an ultra low profile becket thanks to the through-sheave design.

Nylatron® plain bearing Orbit block™ boasts the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options.

Lightweight
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 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. Has a through-sheave becket arrangement. The result? The lowest weight possible. 

Highest working load in its class
The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods.

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. The Dyneema® Link can also be removed and replaced by a shackle, custom lashing or strop.
These links 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. This reduces weight and gives the lowest possible profile while allowing full articulation.
