Hey Bob,

Yes, for a Demco EZ-Latch gooseneck coupler you would want the Demco Gooseneck Coupler Lock # DM88KV. This lock will cover not only the hole for the gooseneck ball but the EZ-Latch as well so that no one can pop open the coupler and take off with your trailer. You would attach the lock to coupler and then slide the bar for the latch through and lock it in place with a padlock (sold separately).

Hey Bob, how did the Demco gooseneck coupler lock work out with your EZ-Latch setup? It sounds like it should give solid protection for both the latch and ball area. Your feedback could help others looking for the same lock.
