50mm Double Dynamic Block - Tii-On

The 50mm Double Dynamic Tii-On Block is designed for high-load purchase systems where maximum strength, reliability, and efficient load handling are essential. 

This block is ideal for keelboat mainsheet systems. Can also be used in backstay and other purchase systems. Developed for use on the Cape 26 mainsheet. 

Ideal for modern soft-attachment rigging systems, the double-sheave configuration allows compact, efficient purchase arrangements while delivering smooth operation and exceptional load-carrying capability. Available with or without a soft shackle.

Key Features:

• 50mm double-sheave Dynamic Block
• Stainless steel head loop for maximum strength and reliability
  
• Ideal for keelboat mainsheet systems
  
• Twin rows of stainless steel ball bearings running on a stainless steel rail
  
• Lightweight and durable construction
  

Installation Notes:

• For maximum strength, the attachment line should pass around the central axle and through the two stainless loops.
• Where possible, use a crossed attachment arrangement to help keep the side cheeks loaded together.
• When using a Tii-Shackle, crossed installation is recommended for higher-load applications.
