Wichard Triple Block 55mm for 12mm Rope

The Wichard 64305 Triple Plain Bearing Block is designed for high-load sailing systems that require multiple rope passes while maintaining reliable and straightforward operation.

Its three 55 mm composite sheaves use a plain bearing system, running on stainless steel bushes. This robust design is specifically intended to withstand high loads and is particularly suitable for applications with relatively static loading.

The triple-sheave configuration makes the 64305 ideal for creating powerful multi-part purchase systems, helping reduce the effort required to control heavily loaded lines.

Swivel Head for Flexible Installation

The swivel head provides greater flexibility when positioning the block and allows it to align more naturally with the direction of the load.

Wichard’s universal head design also provides a wide choice of fastening options, making the block suitable for different deck and rigging configurations.

Strong Marine-Grade Construction

The head configuration and load straps are manufactured from 316L stainless steel, providing high strength and excellent resistance to the marine environment.

Lightweight POM cheeks protect the sheaves, while the sheaves themselves are made from composite material. The terminal fitting is also manufactured from 316L stainless steel.

With an impressive 880 kg working load, 1500 kg breaking load and a total weight of 410 g, the Wichard 64305 offers substantial strength for demanding onboard systems.
