Jeep Gladiator JT Doors 2019 to Present Free Standing Holders Make: Jeep Model: Gladiator JT The Steinjäger portable door holder is easily disassembled and reassembled with the use of six wing nuts. Both stock doors or tube doors are fully supported by the door hanger. Taking up only about 1.25 cubic feet of space, carrying this door hanger with you to an event is very simple. Since the doors are used in the structure of the tube holder, it is normal to have some side to side movement when the hanger is empty. We have included an alignment pin to ease putting the first door in the rack.
