Harken 57mm Black Magic Blocks

Harken 57mm Black Magic Blocks
Used on offshore boats, these strong, lightweight blocks feature Torlon« roller bearings for strength and reduced wear. Rollers are housed in a center cage and stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion.
