    Product Description

    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. 

    Features:

    • Side opening side plate - Easy to rig and remove from sheet
    • 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
    • Thimble at pivot base - Use 1:1 or 2:1 up-down control
    • Machined aluminum inner sideplates - High strength, low weight
    • Soft polyurethane outer side plate bumpers - Protects block and deck

    Uses:

    • Twing, tweaker control for code zero sheets
    • Can be used as a snatch block when combined with a soft shackle
    • Spinnaker sheet and guy control
