These multipurpose blocks are a must on racing yachts of all sizes. Opening side plates make them easy to deploy, allowing crew to quickly fasten them wherever needed—perfect for temporary leads, line deflection, and static line functions requiring small adjustments. A strap soft-attach is fixed on one side, but is easily removable on the other. The strap carries the Blokk's primary load and articulates for a fair lead. The Velcro® strap is permanently attached to one side plate and holds the Blokk securely closed when the side plates are aligned—even under the highest loads. The strap has a broad reflective tab for easier operation with gloves.
Harken composite bearing technology (ULC) ensures sheaves turn smoothly and maintain efficiency under extreme loading. Snap-fit Torlon® bearings carry sideloads. An integral headspacer prevents Hard Lube-anodized aluminum sideplates from deflecting and binding. The wide sheave allows a range of line diameters.
