    I received an early prototype. I’ve had it mounted in the bed of my truck along with the Yeti cooler for about 4 months now. The cooler is still there after 4 months! It wouldn’t have made it a week without the Deny lock. Excellent product that keeps your Yeti safe in public and is very easy to remove and reinstall the chest from the lock. Thanks Jake and team!

    Product is very simple to install, and I have never seen anything more stout. I have a flatbed truck and everyone sees my cooler on the back buckled down with DENY so I know they won’t even try and take it. Keeps my cooler in place so I can get a drink when I need one!

    I have a flatbed truck with three Yeti coolers mounted in it…This is a huge target for “cooler thieves”!! I used to lock them with cable locks, which I guess is better than nothing, but I always worried. After meeting Jake at a show in AZ I bough three Deny locks…now I can rest assured that every time I have to leave my truck the Yeti’s will,still be there when I get back. Thank you Jake!’

    Great product. Well made and solved a major problem for myself. I was able to use it for double duty in securing my Kayak on my truck rack with running the stiff arm through a pewag chain. Can’t recommend this enough if you spend time outdoors and love to have your cooler and ice ready at all times!
