Product Description

75 mm Black Magic® AirBlocks® feature Torlon® roller bearings for strength and reduced wear. The unique center cage separates rollers for less friction. Sideload ball bearings are protected by sculpted aluminum sideplates. Dissimilar metals are isolated to minimize corrosion. Low-load blocks use Delrin® rollers and type 316 stainless steel shackles.

Like all AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single Allen wrench.

Use straphead blocks with LOUPS or straps aligned fore/aft or side to side.

Use for:
Sheets, Halyards, Running backstays and Control lines.
