29mm Wire Upright Lead Bullet Block
This Harken 108 Rope/Wire Upright Lead Block is often used to lead spinnaker pole lift, cunningham, outhaul and other control lines from the mast base.
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.
