The Harken Origin TT multi-purpose rigging plate was designed with this driving principle in mind: improve the rigging and performance of Twin-Tensioned Rope Systems (TTRS).

Unlike rigging plates that use a single bolt system to mount two side-by-side multi-purpose devices, Origin TT employs two quick-release locking pins. This enables independent attention to either of the twin devices managing ropes in the system, while the other remains safely tensioned.
