Locking SledLoxx to deck

Anyone use the newer style Sledloxx on their sled deck? The current design does not allow for a padlock to be used effectively. They are going to be redesigned as I have talked with Robin at Truckboss.

Has anyone found an effective way to lock the Sledloxx? Maybe with a longer shank on the padlock or should I just go to using a chain and lock around the skis and headache rack?

Yea, Wish i would have but I got the Sledloxx for less than I could have bought used superclamps. I should have done more research beforehand obviously. On that note the Sledloxx work incredibly well
