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. For PBB 60/80/100/130.
• Two polyamide washers on pin/ bushing to reduce play between wire terminal and cheeks.
