25 mm Nylon Double Sheave Block, 304 Stainless Steel - MBLA225ND

The Mame Block A2 (304) Marine Sheave Block is available in 11 sizes (25 mm to 50 mm) and is a pulley block with a sheave (the wheel) that guides rope and reduces friction. It is used to change the direction of a rope or to gain mechanical advantage.

The range runs to 11 variants, covering sizes 25 mm to 50 mm.

Made from 304 (A2) stainless steel, a standard austenitic grade with good everyday corrosion resistance. It is a sound choice away from the coast; in chloride-exposed settings, step up to 316 (A4).

In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.
