Bullet Blocks
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 Hard Lube-anodized aluminum sheaves 
for strength and corrosion resistance. Mast exit blocks 
with cams are used for halyard controls and under 
boom mainsheets. 
About Classic blocks: see feature page at beginning of this section.
Sheaves see page 76.
The complete line of Small Boat Classic blocks is available through Harken 
dealers worldwide and online at www.harken.com/en/shop/small-boat-classic/
