Turning block, ball raced, small - 7 mm sheave

Turning block, ball raced, small - 7 mm sheave. SAILSetc design and manufacture. A beautifully simple design of block for lines of 0.6-0.7 mm Ø (SAILSetc D55 or D75). Designed to avoid snagging the sheets.

Suitable for use as a deck mounted turning block in the main winch loop system on 65, RG65, FOOTY and similar small classes. Also suitable for routing sheets around the deck on larger classes if not taking the main winch load. It is important for the ingoing and outgoing lines to be in the plane of the surface to which the block is mounted.

Choose the larger version ref.62-010 for use on IOM, M and similar size classes.

Mount by bolting through the deck with the M2 screw supplied. 15 mm Ø x 4 mm high.

SAILSetc blocks have black plastic bodies, which may be injection moulded, turned, or printed. The sheaves are stainless steel, but not marine grade stainless steel, and have hardened rust-resistant balls. Fasteners provided are marine grade stainless steel. Other metal parts, if any, are marine grade stainless steel.
