Expert Reply:
We have all sort of trailer locks including coupler locks for a-frame trailer couplers. Please refer to the linked page that displays all standard coupler locks.
You can use a universal-fit surround-type lock such as # ML389DAT which fits all ball sizes and that prevents someone from hitching to your trailer by clocking access to the coupler, or a simple latch type lock like # e98889 that prevents the coupler latch (like the one on # CA-5400-B) from being lifted to unlock the coupler.
