25mm Shouldered Block

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.


  • When fitted with a lacing eye (25.17), the block will stand up directly and not flop from side to side
  • This range could be used to create purchasing systems for lifting, garage door mechanisms, storage solutions, etc.


  • Max Rope: 8mm
