Security pin quick-release

When you are on a tour, or if you chage trailers and bikes often, time can be of the essence. The quick-release ball-lock cotter pin upgrade for the Cross-Link trailer coupler lets you quickly and easily attach and detach your trailer from your hitch/bike. It is just as secure as the existing safety pin and cotter pin, but makes the swap a whole lot easier. No more fumbling with the cotter pin lock ring!
