Keelboat / Etchells / Blocks / Wire Blocks

Specifically intended for use where wire lines are subjected to low rotational high loads.


The range uses stainless-steel side cheeks and a single row of spaced stainless-steel ball bearings in the sheave to give maximum strength in the smallest form possible.


Available with different accessories including hooks, beckets, swivels and shackles giving a whole range of choices to suit different applications.


Bearings â€“ A single row of spaced stainless steel ball bearing run on a stainless steel axle. This allows the width of the block to be as narrow as possible whilst still offering excellent rolling speeds and high working loads.


Body – Formed in stainless steel for a lightweight yet robust frame.


Maximum Working Load â€“ If exceeded the block may not perform as designed.


Breaking Load â€“ The load at which a major block failure is likely to occur.
