Just put the new rack on yesterday, and go to play with it, take the padlock out and whatnot, and ever since I have not been able to get it to lock back. Immediate thought was my stupidity, but have since ruled that out (hopefully). Went and bought a new lock to see if that was the case and no luck. The problem seems that when I rotate it back to the lock position, I am unable to get the lock pushed in far enough to catch. I think it either has something to do with the piece of aluminum the lock is on not letting the lock get pushed in far enough or something of that nature. Dont get me wrong, I love the thing and it is built like a tank. Anyone else ever had this problem? Any Ideas? Thanks in advance.
