The 25mm plain bearing block range is one of SeaSure'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.

  • The 00.21 can be used to create a 4:1 purchase system to aid in lifting heavier objects and decrease the load on the rope
