These multipurpose blocks are a must on racing yachts of all sizes. Opening sideplates 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 strop soft-attach is fixed on one side, but is easily removable on the other. The strop carries the block’s primary load and articulates for a fair lead. The Velcro® strap is permanently attached to one sideplate and holds the block securely closed when sideplates 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.
