When deck hardware must manage heavy loads and resist saltwater corrosion, this block provides a proven, low-maintenance solution. It keeps your lines controlled and your rigging predictable under typical cruising and racing conditions.

• 54mm x 17mm sheaves sized for larger control lines and mainsheet systems
• 316 stainless steel load frame and internal components for corrosion resistance
• Safe Working Load (SWL) 750kg and break load 1500kg for quantifiable strength
• Plain bearing sheaves compatible with up to 12mm (7/16") rope

Compared to ball bearing blocks this plain bearing double block offers simpler, robust performance for high-load, lower-rotation applications and is compatible with Barton ball bearing mainsheet traveller systems when used in matching positions. Use it for mainsheets, halyards, or control lines where durability and tested load ratings matter.

Materials and testing signals: marine-grade 316 stainless steel construction, specified SWL 750kg and break load 1500kg.
