Hi Robert; the pin lock that comes with the # ML44VR will work but I've seen some issues with fitment for the surround lock on your coupler style because of the shape and design. Some people have had success with it on that Demco eZ-latch but I'm not overly confident.
Are you wanting to upgrade from your current lock? You could still get the Master Lock Hitch Receiver and Coupler Latch Lock Set # 2848DAT which excludes the surround lock so those are keyed alike and then get a different surround style. For serious protection I recommend the BulletProof Hitches Extreme Duty Coupler Lock # BPH96VR. This lock is pretty tough to defeat and we have tested it on that same coupler so we know it fits for sure.

Hey Robert, how did things turn out with the coupler lock for your Demco hitch? Did the BulletProof lock end up being the better fit? Your update could make it easier for the next person with that same coupler style.
