Is very unique in that it provides you with the ability to use it by itself, only needing a four hole adapter plate in the bottom of the socket. This saves height, weight and provides a simple, quick shower or swim leg with no lock mechanism to worry about. But it is also integratable so that it can be used with some Bulldog® shuttle locks, providing safety and stability. The Lanyard System includes one special 12” pylon with bonded tube clamp and one special short pin with a string bonded to it and a socket attachable rope tie off.
