ABSTRACT:
An improved stabilizer jack for securement to the underside of a recreational vehicle. The jack includes a channel frame formed with downwardly and inwardly turned sidewalls terminating in spaced apart retaining edges forming a track. A hanger bracket is mounted to the frame having a pair of laterally opposite projecting axle tabs and a screw is rotatably mounted to the bracket and restrained against longitudinal movement. A trunnion plate is carried in the track and includes a threaded bore for engaging the screw. A support leg projects downwardly and outwardly from the track and has one end thereof pivotally carried from the trunnion plate, the medial portion of the support leg being pivotally connected to one end of a strut. The opposite end of the strut is formed with upwardly turned retainer flanges spaced laterally apart, the flanges each including an axle tab bore. The hanger bracket axle tabs are received in the axle tab bores so that the upwardly turned retainer flanges are received in closed spaced relation between the inwardly turned retaining edges of the channel frame to constrain the flanges from lateral outward spreading to retain the axle tab bores on the axle tabs.
