The Harken 100 29mm Double Wire Bullet Block is a heavy-duty block with 250 pounds more load capacity than the light-duty 084 Double Block.
Designed for vangs, outhauls or shrouds where wire is used or for rope where loads are too high for regular bullet blocks. Roller bearings handle high loads better than ball bearings. Sheaves are PTFE-impregnated, Hardkote anodized aluminum for strength. They deliver dependable fast trim and release under high or low loads.
A range of styles lets these blocks adapt to almost all control line applications. Ideal for cunninghams, vangs, outhauls, traveler controls, spinnaker controls, barberhaulers, etc.

Corrosion-resistant stainless steel straps reinforce these blocks
