Wichard Triple Block 45mm with Cam

The Wichard 63308 Triple Plain Bearing Block combines three sheaves, a swivel head, a becket and a cam cleat in one compact unit, making it particularly useful for powerful multi-part rope systems on sailing boats.

Its three 45 mm composite sheaves run on stainless steel bushes. This plain bearing design is simple, strong and specifically developed by Wichard to withstand high loads, particularly in relatively static applications.

Swivel Head, Becket & Cam Cleat

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

The integrated becket provides an additional attachment point for the rope, making it easier to create multi-part purchase systems with increased mechanical advantage.

An integrated cam cleat allows the working line to be secured and released conveniently, making the block particularly practical in applications where frequent adjustment and control are required.

This combination makes the 63308 especially well suited to mainsheet systems and boom vangs, the two applications specifically recommended by Wichard.

Built for the Marine Environment

The head configuration and load straps are manufactured from 316L stainless steel, providing excellent strength and corrosion resistance.

The block also features POM cheeks, a composite cam saddle and composite sheaves, while the terminal fitting is manufactured from 316L stainless steel. This combination provides a strong yet relatively lightweight construction suitable for demanding marine use.
