(Discontinued by Harken) Please see harken 3195 as a replacement:
Use 57 mm Black Magic® AirBlocks® on offshore boats. These strong, lightweight blocks are sculpted aluminum, with Torlon® rollers and carbon-black balls for strength and UV protection. Rollers are housed in a unique center cage and are isolated for less friction. Blocks feature a three-way head system and come in high- and low-load configurations. Use it for sheets, halyards, running backstays and control lines.
