Wichard 64109 Single Block 55mm with Clevis

The Wichard 64109 Single Plain Bearing Block is designed for sailing applications where strength, reliability and secure attachment are essential.

Its 55 mm composite sheave runs directly on a stainless steel bush, creating a simple and robust plain bearing system. Wichard designed this range to withstand high loads and recommends it particularly for relatively static operations.

Designed for 12 mm rope, the 64109 combines high load capacity with a compact format. Its swivel with clevis provides a secure connection to compatible deck or rigging fittings while allowing the block to rotate and align more naturally with the direction of the load.

Swivel with Clevis Attachment

The clevis connection provides a strong and practical attachment solution for rigging systems where a pin-type connection is required.

Combined with the swivel, it gives the block greater freedom of movement and helps maintain better alignment as the direction of the load changes. Wichard’s universal head design also provides a wide choice of fastening possibilities.

Built for High Loads

The Wichard 64109 offers a working load of 640 kg and a breaking load of 1000 kg, while weighing only 159 g.

The head configuration and load straps are manufactured from 316L stainless steel, providing strength and excellent corrosion resistance for marine use. Lightweight POM cheeks protect the composite sheave without adding unnecessary weight.
