Runners are designed for use on the running backstays of offshore boats, allowing for precise adjustment of mast bend to accommodate varying wind conditions. The construction features integrated sideplate bails and recessed cotter keys, creating a smooth profile that prevents snagging on lifelines. Hard Lube-anodized sideplates and sheaves provide maximum UV protection and a smooth surface finish. A center cage ensures that Torlon roller bearings remain separated and parallel, significantly reducing friction during operation.
