CURT Adjustable Sleeve-Lock Channel Coupler

I purchased this Hitch Lock to secure my bike rack to a 1 1/4 inch receiver hitch. It works well and appears to be difficult for a thief to break off. The only downside is the amount of sideways play in the Lock because of the excessive length of the Lock's bar. To remedy this, I purchased 12 washers (from the local hardware) with 1/2 inch center holes. I placed 6 washers on the Lock's bar on each side of the receiver hitch...problem solved, no more play. (The lack of play also makes it more difficult to surreptitiously remove the Lock).

I did not like the gray cover so painted black and now I am very satisfied with purchase. It helps keep thieves from stealing your nice step hitch and local lock can not compare to this lock hitch. I would recommend to anyone.
