Ronstan Headboard Shackle 3/16 inch

Specifically designed for halyard applications, these shackles feature a closed eye section at the top to retain the halyard at all times and a captive shackle pin to avoid accidental dropping and loss. The halyard retaining pin is removable to allow fitting of a pre-spliced halyard eye end, and the shackle pin is engaged by a quick action pin that requires only one quarter turn to tighten or loosen, has an anti-vibration retaining lug and a long lever head for easy one handed engagement.
