Lewmar's Racing range is designed for high strength to weight ratio and smooth rolling for rapid line handling. Blocks with posts have a three-position head allowing the shackle to be locked in-line, perpendicular to the sheave or to spin freely.
The 80mm Racing Footblocks have composite sheaves that run on dual Delrin races while the 80mm High Load Racing Footblocks have Torlon rollers with Delrin ball side thrust races, alloy cheeks, and alloy sheaves. Standard load footblocks with jammers have friction cams and high load footblocks with jammers have spring cams.
This block rotates clockwise. The LW29906821 rotates counterclockwise and is for the port side.
