If you're not sure the lock will fit your coupler - just call them!
I discovered Altor locks after watching the LockPickingLawyer on Youtube. I am very pleased with all 25 pounds of it! The customer service is outstanding. If I get another trailer, then I'll buy another Altor lock.
This is very heavy duty as described, it would probably be easier to cut then weld a new tongue on instead of trying to remove the "ICON"
