Harken 40mm Bumper - #3451

Harken 40mm Bumper (Bumper Only)

Harken’s new Aperture Rings are designed to provide increased inside diameters for the same load ratings. That extra aperture allows sailors to rig both 2:1 up/down and 2:1 in/out control systems while still leaving ample room for free jib sheet travel. The outer bumper protects accidental dents, marks and scratches all over your boat—including your mast during tacks or sail changes. Aperture rings are hardcoat-anodized aluminum so they don’t corrode or wear.

Aperture Rings are available with or without bumpers.
