Selden 45mm High load Block
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
The sheave is V-shaped for wires. Light holes to reduce weight
Two polyamide washers on pin/bushing to reduce play between wire terminal and cheeks
Designed for wire applications subject to rig loads, e.g. backstays
