The Kuat Locking Hitch Pin is made specifically for Kuat Racks. The lock comes with a dust cap, three keys and a bottle opener. Works on the following racks: Alpha 1.25, Beta 1.25 and all Sherpa racks.
I have had the hitch lock for some time now for use on my motorcycle hitch and it works perfectly. At first I was concerned at how long the pin was but the length seems to keep the lock cleaner and more assessable for locking and unlocking. I am well pleased!
