No lock yet, but there will be. The bolt holding down each tire will be changed to a drop pin. Sort of like the pin that holds the hitch in the receiver. The middle part will have a lock on it.
The rack is rated at 500 pounds and cost me $72.00. The 2 braces that go up to the tire mount cost a total of $9.00 cut to size. The track was a free piece that was laying around.
I will be adding lights to the rack sometime also.
