Ratchet Blocks

Product catalog summary

Introduction
This document introduces the second generation of manual ratchet blocks, focusing on improved grip and switch functionality. These blocks are primarily used in dynamic applications such as sheets on dinghies and keelboats. When activated, the ratchet locks the sheave in one direction, allowing sailors to relax without cleating the line.

Design and Variants
The ratchet blocks are designed with lightweight Delrin ball bearings. New single block versions are available with either a composite or aluminium sheave, the latter providing more grip and accommodating thinner lines. The product range includes various models such as R60+ SINGLE, RATCHET, R60 TRIPLE/BECKET-CAM, and others, each with specific features and applications.

Specifications
The document provides detailed specifications for each model, including weight, safe working load, breaking load, maximum line size, and fasteners required. For example, the R60 SINGLE, RATCHET (406-350-01R) has a weight of 121g, a safe working load of 250kg, and a breaking load of 500kg, suitable for a maximum line size of 10mm.
