HARKEN BLACK MAGIC SINGLE BLOCK 125MM
The entire line of Black Magic Air blocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same. These strong, lightweight blocks feature free-rolling high-load Torlon® roller bearings for a high strength-to weight ratio.
Like all Black Magic blocks, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.
