This is the Yanker Tool 'BASIC' model.
The patented design opens the Jost 5th wheel release, and all others. Jost is the one you have to reach in under the trailer, over/between the drive wheels, lift the handle vertically, then push it toward the cab, and then pull it out. Pulling the Jost release can be very difficult. Pulling all 5th wheels is risky for injuries. Extended range motion, outside of your power zone, reaching far under the trailer. Vicious rotator cuff injuries are well known to happen pulling the release. Also wrist, elbow, arm, and back injuries are well known to result from pulling the 5th wheel release. Pulling a 'straight pull' release is hazardous enough. Add the multiple torque demands of the Jost, and the risk of injury increases.
The BASIC model is good for occasional or light duty. It's lighter, shorter, and the handle is smaller than the XHD. Built in 3/8" steel, while the XHD is much beefier in 1/2" steel. The Basic has a 'Chrome-like' finish. If you drop and hook with any frequency, you really want to look at the XHD model. It's the "Driver's Choice" almost every time.
Not sure the Yanker Tool is worth it? Just ask a a driver who has had a rotator cuff injury. They'll tell you to buy the Yanker Tool as fast as you possibly can to avoid going through that injury. It's the cheapest, and best insurance you'll ever buy. Not to mention keeping you out of the mud, grease, slush, and filth involved in pulling the release without a Yanker Tool.
