A screw collar pin is a feature of the Green Pin® Bow Shackle SC bow shackle. The screw pin facilitates rapid (dis)assembly, rendering the shackle ideal for rigging tasks involving frequent installation and disassembly. One-leg and multi-leg systems can both be utilized with the Green Pin® Bow Shackle SC. The shackle's long-term resilience is ensured by its galvanization. Because the screw thread is concealed inside a chamber, the shackle's design lessens the wear on (wire) rope.
