25mm Treble Block with V-Jam

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. 


  • This range could be used to create purchasing systems for lifting, garage door mechanisms, storage solutions, etc.
  • The 00.35 can be used to create a 6:1 purchase system to aid in lifting heavier objects and decrease the load on the rope. The V jammer can be used to cleat the rope at any point during lifting or tension


  • Max Rope: 8mm
  • Breaking Load: 1250kg
