Sometimes you just have to be creative...since set-ups can vary so much. Helps me to wander around hardware & home improvement stores, to get ideas.
And nothing wrong with asking that pet store you saw them in.

Think I might try to be creative and drill the holes that the pins go in, for the VE racks, through the holes and tub handle and just use those cable suitcase combination locks.
