"Low-friction Harken 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."^^<http://www.w3.org/2001/XMLSchema#string>
