How does the coupler attach to a 3-inch trailer channel?

What safety and locking features does the trigger latch provide?

The coupler uses a positive trigger latch to clamp around a 2-inch ball and reduce the risk of accidental detachment. The latch includes a hole to accept a standard safety pin or a pad-style coupler lock (sold separately), providing an extra layer of security when towing or storing the trailer.
