Habco has been in development of a 40-inch off aircraft tire cage. This is a one of a kind unit, built on the same design as Habco's other four cages. The design is the only U.S. Army tested and approved aircraft tire cage available. The tire cages exceed the requirements and have proven to save life and limb. Don't leave safety to chance. Even though the probability of a tire failure is low, the consequences are severe and fatal. The risk factor is too high to choose an inadequate tire cage.
