Hello Bob, thanks for reaching out. We do have a lock that will work with the etrailer Adjustable 2-Ball Mount # e66PR. For that I recommend the following:

This can be used to lock the ball mount to your hitch. You can order a second one keyed alike to lock the ball into the channel. The locking pin is a bit longer than the current adjustment pins, but it will still work great for adding security and to help keep the ball mount from wandering off.

I purchased this Hitch and it's great! I was a bit hesitant at first at the idea of needing three Locks or Pins, but am so glad I did. First, you definitely need (2) Locks, or, a Lock and a Pin to secure the Ball Assembly. And then, either a Lock or a Pin on your vehicle receiver. Any combination of Locks/Pins to total (3) works great. Like probably other people, I had more than one Receiver/Ball for the different trailers that I tow (boat, UTV trailer, etc.). And, while it's no big deal switching them out, I found that the Adjustable Two Ball Hitch actually allows me to kind of fine-tune tongue weight better than using my (old) individual hitches. I use the Hitch throughout the year and it's a breeze moving between trailers by adjusting the height of the ball. Definitely recommend this Hitch.

@Barry Thanks for the detailed write-up, that’s great feedback. You’re exactly right on the locking setup. Using two locks (or a lock and pin) on the ball assembly plus a lock or pin at the receiver is the recommended approach, and running three total gives you maximum security and peace of mind. Glad to hear the adjustable two-ball design has been such an upgrade for you, especially being able to fine-tune hitch height and tongue weight when switching between different trailers. That versatility is one of the big advantages of this style hitch. Thanks again for sharing your experience, it’s very helpful for others considering the same setup.

I purchased this hitch for my 2025 palisades love it because the two different ball sizes make it so easy to haul both boats
