The air hook easily attaches to the car's tailgate lock, allowing the tailgate to remain slightly ajar and allowing air to circulate. Adjustable length. Made of galvanized metal. The air hook fits almost all car makes and models, but not electric tailgates.
Although the air hook improves the ventilation of a parked car, it is not enough to keep the car cool in the summer heat. Do not leave your pet in a hot car, even for a short trip to the store, as heat stroke can be life-threatening for the animal.
