Product Details

1 Ton Twing Block

The Twing block features a spring-loaded side opening mechanism for true one-handed rigging, even while wearing sailing gloves. Black anodized aluminum sideplates are edged with robust bumpers to protect the block, topsides, and deck. The sheave is aluminum rolling on a bearing system shared with Harken's existing 2.3T high-load snatch block.

  • Spring loaded button release - Quick one-handed rigging
  • Anti-capsize bar - Keeps sheave aligned on sheet
  • ULC main bearing - Sheave turns smoothly under extreme loading
  • Sideload balls - Carry loads especially when the block is not aligned in light air
