Black Magic® footblocks carry some of the highest
loads imposed by running rigging. The Torlon® rollers on these lightweight, free-running blocks
are housed in a center cage, with no contact
between bearings. UV-resistant, carbon-black
Delrin® balls handle sideloads.
Either metric or imperial flathead fasteners may
be used for mounting and are not exposed.
