The etrailer Adjustable Trailer Coupler Latch # e98883 is a really great lock solution for the pin hole of the latch on the Bulldog Cast Head Coupler # BD4420000317 that you referenced. It will fit snugly to the latch assembly for a tight and secure fit that would be much harder to defeat than a pin lock with excess span on either side of the latch.
