APS - Antal Twin Halyard Block

Antal Twin Halyard Block

Antal’s Twin Halyard Block is designed specifically for use with a 2:1 main halyard. The block features an extremely high working load in relationship to its size. The block is hardly larger, and weighs little more, than a standard main halyard shackle with comparable working load. The extremely small sheave includes a High Load Composite Fibre Bushing.

This lightweight block is machined from a solid piece of “High-resistance” 17-4-PH Stainless Steel, with a captive and self-locking pin. Three sizes are available for boats from approximately 40 to 65 ft.
