    Does this work on a king pin that has a capture plate for the super glide hitch?
    Whether or not this stabilizer can be used will depend on the physical design of the capture plate. The cup on this stabilizer has an inside diameter of 2.94" and is 2.87" deep. Some owner's trim down the height of the cup or set a woodblock inside for clearance.

    If the lowest height of 42" is too tall, then a tripod with a shorter starting height would be recommended such as #64850. This tripod has a starting height of 35" and can adjust to 55". Or #71258 which starts at 37" and can adjust to 60" in height.

    Leg extensions are available for most Ultra-Fab tripod stabilizers to increase height if the top height happens to be too short. However, the tripods can not be modified for a shorter height, if modification is performed. Any resulting damage, injury, or death that may incur is the sole responsibility of the owner.
