Large: This Stainless S-hook is 1/4" thick. It is used on all our sails to connect the downhaul grommet of the sail to a small block such as the RF-20101. The hook can be twisted open to install the block for a very tidy assembly.
Small: This smaller s-hook is 3/16" diameter and is perfect for attaching the boom vang to a Spindrift boom. Also great for any control line that needs quick rigging.
