Used on offshore boats, these strong, lightweight blocks feature TorlonØ 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.
Low-load blocks use TorlonØ rollers and 316 stainless steel shackles. Standard blocks have 17-4 PH stainless headposts.
Like all Black Magic blocks, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.
