Harken 3224 - 57mm Black Magic Runner Block
Designed for running backstays, this runner block adjusts mast bend under varying wind conditions. Recessed cotter keys and integrated sideplate bails create a smooth profile that avoids snagging lifelines. Hard Lube-anodized sideplates and sheaves provide UV protection, and the center cage ensures Torlon® roller bearings remain separated and parallel, reducing friction.
