YETI coolers equipped with YETI Bear Proof Locks have been thoroughly tested in both controlled bear simulations and with wild grizzly bears. With locks in the integrated padlock ports on two corners of a YETI Tundra cooler grizzlies get nothing but frustrated. Fits all Tundra and Roadie models. Extra-long shank Master lock. (Set of 2).
The locks are great for their intended purpose: theft deterrent and prevention of creatures opening the lid. Like any lock, it's subject to the will of the attack against them. Thankfully woodland critters are savvy enough to pick locks.
This is my second set of locks I purchased for coolers. This one is for or a my Yeti 35. The first set of locks I had for a larger cooler has survived the winter, albeit covered, and work grreat with the Yeti locking cable.
