57 mm Aluminum Footblock - Lockoff
The entire line of Black Magic AirBlocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same.Carrying some of the highest loads imposed by running rigging, these strong, lightweight blocks feature Torlon roller bearings housed in a center cage. Rollers stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion. Blocks are easily disassembled with a single hex wrench.Use footblocks to redirect lines on the deck. Footblocks with lockoffs temporarily secure sheets.Either metric or imperial flathead fasteners may be used for mounting and are not exposed.
