Wichard Cheek Block 45mm for 10mm Rope

Reliable line control is essential when loads increase. The Wichard 63120 Cheek Block combines a simple plain-bearing system with durable marine-grade materials to provide dependable performance without unnecessary weight.

The 45 mm sheave runs directly on a stainless steel bush, creating a strong and straightforward mechanism particularly suited to applications where the block operates under significant or relatively static loads. The lightweight cheeks protect the sheave while keeping the complete block to only 73 g.

Designed as a cheek block, it provides a practical solution when a line needs to be redirected along the deck or another suitable mounting surface. Wichard specifically recommends this configuration for genoa sheet applications.

Built for Marine Loads

The structural components use 316L stainless steel, including the head configuration and load straps, providing excellent suitability for the marine environment. The block also features POM cheeks and a composite sheave, creating a balance of strength, low weight and durability.

With a working load of 400 kg and a breaking load of 900 kg, this compact block is designed to handle demanding sailing loads while maintaining a neat installation.
