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.
