25mm Single Block with Becket - Metal Sheave

Sea Sure's 25mm Brass sheave blocks are for medium-high load applications with slow running rope. The range works well with dyneema or wire rope as the stainless steel side plates stop high abrasive ropes from cutting in. The becket allows you to attach the wire or rope to the block so that a 2:1 purchase system can be made to reduce the weight on the rope when lifting.
