This lockset is specially designed for the Rebellion XD ball mount and replaces standard clips and hitch pin for increased security. Featuring a hitch and tongue lock, the hitch lock is manufactured from stainless steel for lasting rust resistance and fits 2"" or 2-1/2"" receiver tubes. For superior weather resistance, the tongue lock is constructed from cast aluminum and fits over the vertical-shank pins of the Rebellion XD to lock the attachment into place. Both locks feature a 1/4-turn activation for convenience, and they are keyed alike for easy, one-key operation. The lock set secures both Rebellion XD tongue and shank and the locks keyed alike for convenient one-key operation. The Rebellion XD is not included in this package and must be purchased separately.
