CURT 5th wheel adapter plates are a fast, dependable way to convert your gooseneck trailer hitch into a set of 5th wheel rails to accept a 5th wheel hitch and switch back again. With gooseneck installation brackets and a gooseneck hitch already mounted, the adapter plate post simply mounts into the gooseneck trailer ball hole using a solid shank and is secured with the locking mechanism provided by the gooseneck hitch. One of the most attractive features about CURT 5th wheel adapter plates is that they are practically instantaneous: insert the shank, apply the locking mechanism and just like that you have a sturdy pair of 5th wheel rails. This CURT 5th wheel adapter plate features a round shank and is compatible with CURT Double Lock EZr gooseneck hitches. It features a gross trailer weight capacity of 20,000 lbs., allowing it to adapt and accept a number of 5th wheel hitches up to 20K. This 5th wheel adapter plate offers a simple pin-and-clip conversion for gooseneck hitches and has multiple mounting points to accept either 5th wheel legs or a 5th wheel roller.
