We hit some square edge bumps on an over-pass that dislodged the pantry shelves and they fell. Luckily no damage. I think that when we hit a series of bumps that causes a porpousing action, that the shelves jump up and the clip's fall out of the vertial adjustable runners. I put new shelf clips in, (this is not the first time the shelves have fell). Then I stuffed pillows between the shelves to help with the bouncing. I'm thinking I should drill and screw the clips to the wall bracket and then the shelves to the clipsAny suggestions.
