The RVGC-F is the fixed version 5th wheel to gooseneck king pin box.  Most 5th wheel trailer frames have 3 different hole patterns for a small height adjustment which gives you about 3" of adjustment where it bolts to the trailer frame.

RVGC-4105F   fits "Lippert" king pin box models 1621, and 0719

Popup Gooseneck Hitch products are made in the USA.

If you want to know the location of the gooseneck trailer coupler using the new king pin box (because these king pin boxes fit several different models) below is how to calculate the location of the (top center of the gooseneck ball) coupler.

 From the center of the most forward and lower bolt hole (on the king pin box of your trailer) measure forward 19-3/32” and down 19”-15/32” for the fixed model.  This will give you the location of the center and top of your gooseneck ball with your new 5th wheel king pin box.
