Snatch blocks are offered in standard and high-load configurations and are used on offshore boats 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.
Harken Snatch blocks feature low-friction roller/ball bearing sheaves and a unique push-button latch for one-handed operation. Urethane sideplates prevent damage to decks, spars, and cabin houses. An integral bail allows blocks to hang from lifelines with shockcord. Snap shackles attach to padeyes and bails, while trunnion shackles attach to toerails and other fixtures.
High-Load Snatch Blocks
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.
