XS-100-B SHEAVE OPTIONS
4 SHEAVE OPTIONS TO FIT XS-100-B BLOCKS
Four sheave options are available for the XS-100-B blocks: polished groove aluminum, urethane lined, ductile iron, or nylon. All are 7 in. x 3 in., heat treated for strength and extended life, and finished with precision machining. All turn on low-friction, sealed, lubricated-for-life ball bearings, which render 98% efficiency and assure long-term reliability and smooth, minimum-load stringing. These sheaves are interchangeable with any other in an XS-100 B frame.
