b'NEW 1250, 1250.ILCA25 mm Fly Blocks This addition to our small but mighty Fly block assortment has been developed to increase the efficiency and working load capacity of the top block in our evolving ILCA 6 and ILCA 7 boom vang systems. Its unique design allows integral attachment to a new-generation vang key. In non-ILCA applications, the block can be attached without the vang key using the included clevis pin and ring ding. The large hole in the bearing axle was designed to accommodate a soft becket attachment point. The sideplates are anodized aluminum. The sheave and inner bearing race are stainless steel as are the 15 bearing balls per side, which roll dual cup-shaped races.1250.ILCA 1250Sheave Max line Maximum BreakingPartLength Weight workingload loadNo .
