Sheave Boxes - 30, 40 & 50mm
Ronstan manufactures a range of sheave boxes for use with rope and wire. Their plain-bearing sheaves are ideal for halyards and other applications where high-static loads are likely to be encountered. Sheave boxes are perfect for minimizing friction and chafing in applications where lines (rope or wire) need to be led through decks, bulkheads or spars.
