Schaefer's snap shackles are designed for maximum strength with minimal weight. The enlarged throat and hinge area handles shear and twisting movements more effectively than smaller designs. The smooth shackle arc prevents jamming against pad eyes or sail grommets to ensure easy attachment and release. Sure-release action results from a positive stop plunger pin with a shear-proof pulling ring and accurately aligned deep slot hinge.
