The Harken 183 29mm Single Wire Bullet Block is a heavy-duty swivel block with 200 pounds more load capacity than the light-duty 166 Single 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.
