The 25mm plain bearing block range is one of Sea Sure's oldest and best selling ranges. The range uses marine grade stainless steel side plates and rivets with an arnite (plastic) sheave which is incredibly hard wearing and light.This range could be used to create purchase systems for lifting, garage door mechanisms, storage solutions etc. The Integral swivel allows for the rope to follow the changing direction on the incoming rope so that the rope doesn't twist and bind up. Max Rope 8mm Breaking Load 700KG
