Redesigned with a sleek look the Black Magic Air blocks has their same unique, performance-packed engineering as ever.
Feature Torlon® roller bearings which stay parallel for low-friction efficiency housed in a center cage; the block carry some of the highest loads imposed by running rigging.
Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Blocks are easily disassembled with a single hex wrench. Dissimilar metals are isolated to minimize corrosion.
Either metric or imperial flathead fasteners may be used for mounting and are not exposed.
