Swivel Double Sheave Block With Bridge Material: SS304/SS316 Size:25mm/32mm/50mm Surface Treatment:"EP" (Electro Polished) Swivel Double Sheave Block With Bridge are compact and lightweight multi-purpose snatch blocks fastened with a loop. The short standard loop minimizes damage to the deck, hull or superstructure. Longer loops are available to extend the range of use and allow the block to swivel. GMT Blocks are available with plain bearings or ball bearings. The ball bearing blocks in fact have a two stage bearing. At lower loads the ball bearing minimizes friction, at higher loads the plain bearing comes into effect. Ideal for small marine and industrial rope applications.
