Schaefer's Twin Sheet Lead Blocks allow for twin sheets through it's wide flared sheave permitting easy sail changes. The Cage and Slide body are computer machined resulting in incredible strength and precision. Each Block provides a low profile articulating sheave for a proper lead from the sail through the block and into your cockpit. Sheaves are hardcoat anodized aluminum running on the low friction Nomex™/Teflon™ Bearing. The New 32-81 features a canted design centering the load on the machined aluminum slide. In addition, the aluminum sheave runs on the Nomex™/Teflon™ Bearing as well as Delrin™ Ball Bearings for a very strong and smooth lead. Finally, the addition of two S.S. springs keeps the block upright when not in use.
