The whole "composite fibre" range uses
sheaves on composite fibre bearings
and double self-captive Delrin ball thrust
The sheaves are easy to dismantle for cleaning
and need no lubrication.
The range of Web Blocks is designed to achieve minimum weight while retaining strength and durability.
The 17-4-PH high-strength stainless steel coupling means the block can be tied with webbing or thin Spectra or Kevlar lines giving the lightest connection possible. "Strengthened" (/Z) models suitable to also higher loads.
