How frustrating is it when you get back to your vehicle after a long day on the water only to find someone has pinched your shackle off your trailer winch. With the new anti theft retaining clips from Snap-D the chances of that happening are now significantly reduced. These Snap-D retaining clips are a cost effective and simple way of preserving how long your D or bow shackle stays to your chain. It also prevents your Snap-D shackles from accidentally falling out of your chain while the pin isn't closed.
