"Harken's low-friction Big Bullet Blocks have a huge range of uses. Compact and lightweight, they trim and release fast under high or low loads on free-rolling, Delrin ball bearings. Sheaves and sideplates are UV-stabilized with carbon-black additive for maximum protection. Just because \uFF93Big\uFF94 is in the name, doesn't mean that they are for use on big boats. Use them on dinghies and sport boats.They have a sheave diameter of 1 \uFFBD \uFF93, or 38 mm."^^<http://www.w3.org/2001/XMLSchema#string>
