All the models of the UTV Overhead Gun Case Holders use the patented Quick-Draw Overhead Gun Rack “opposing forces” installation system. However, the cushioned holding clips are designed to hold ONE firearm enclosed in a soft case. In some states and in Canada, firearms are required to be enclosed in a case when being transported. Be sure to check the laws in your area that apply to transporting firearms. The best method of insuring proper fit of Quick-Draw Overhead Gun Case Racks is to measure the distance between the front and rear roll bars in the top of the UTV.
