Ronstan RF6600 Halyard Shackle

Description

This is a great halyard shackle designed for use on mid-size racers / cruisers.  Previously used on a Sabre 38.  The pin is captive so you cannot lose it when open. The line hole will accept up to 5/8" line, but you are most likely to use 3/8".
When I got a new halyard made I opted for a new Wichard shackle. But I actually prefer the Ronstan shackle since it is easier to get a secure grip on it and has a larger pin end to grip and twist.
