These blocks are optimised for wires or Dyneema/Spectra core.
- Stainless steel, electro polished cheeks, anodised aluminium sheave and polymer plain bearing bushing.
- Outer side plates to increase breaking load – but still optimising the weight.
- Two polyamide washers on pin/bushing to reduce play between wire terminal and cheeks.
- Applications: Designed for wire applications subject to rig loads, e.g. backstays.
