the safe,'no muss-no fuss' key to Jost© safety catch fifth 5th wheel release operation.

The Yost Yanker (patent pending) performs the 'up-over-and out' motion the Jost© safety catch 5th wheel release mechanisms require at uncoupling.  Simply hook the 'thumb' of the Yanker into the Jost© release pull handle, set the 'foot' of the Yanker onto the frame rail, turn it like a key, and then pull outward as usual.  With the Yanker this release operation is performed close to your body, while standing upright, beside the rig instead of beneath it, all while maintaining stable footing. 
You can use your whole body to pull the handle instead of just one stretched out arm that is also simultaneously lifting and pushing forward.  This makes the release operation much easier to perform and your exposure to rotator cuff and lumbar injury is hugely diminished. An injury costs everyone time and money.

You, your body, and your clothing will all be happier with a Yost Yanker.  We guarantee it.
  • No more fighting to lift, push forward, and then pull out while you are off-balance and hyper-extended, all while using just one hand.
  • No more reaching in three feet to grab the 5th wheel release, while squeezed in over the wheels and under the trailer.
  • No more ruined clothing from grease, mud, slush, and general road filth.
  • No more major risk of rotator cuff damage, pulling a muscle, a slip and fall, or worse.

Even if you don't have the reach of a basketball center and the power of a quarterback, uncoupling a Jost© 5th wheel safety catch release is no longer a problem!  The Yost Yanker is the great equalizer.
Try it.  You're going to like how it works.  We guarantee it.
