Harken Low-profile Dinghy blocks are compact and lightweight, with fast trim and release under high or low loads. Blocks are designed for dinghies and control lines on larger boats. Do not use light-duty Dinghy blocks on heavy course racing keelboats, scows, or catamarans.
Free-rolling Delrin® ball bearings, sheave and sideplates UV-stabilized with carbon-black additive for maximum protection. High-strength stainless steel straps reinforce blocks.
