E Scow Spinnaker Halyard Sheave - Harken 29mm Wire Through-Deck bullet Block

E Scow spinnaker halyard sheave. We recommend buying these in conjunction with the E Scow Spinnaker halyard cover plate. The cover plate protects the sheave and reduces friction and wear on the spinnaker halyard.

Low-friction Bullet blocks lead control lines aft. They are compact and lightweight, with fast trim and release under high or low loads. A range of styles lets these blocks adapt to almost all control line applications. Wire Bullet blocks use roller bearings to carry higher loads and feature hardcoat-anodized PTFE impregnated aluminum sheaves for strength and corrosion resistance.
