What is the purpose of the integrated swivel?

The integrated swivel on this block ensures that it can align correctly with the direction of the load. This helps to reduce friction and wear on the line and the block itself, optimizing system efficiency and longevity.

What does the 'becket' feature provide?

The becket on the Harken 57mm Carbo Single Ratchet Block serves as a secure attachment point. It is typically used to fix the standing end of a line, which is essential for constructing multi-part tackle systems to achieve mechanical advantage.

What is the sheave diameter of this block?

This Harken block features a 57mm sheave. This dimension is a key specification for determining the appropriate line size and overall capacity of the block within a rigging system.
