Used Handyman service.  Cart has 4 doors, one door in back does not latch properly.  Cart was to store bird seed in canisters.  Squirrel got through loose back door, ruined my canisters & ate the seeds.  I put a thick board against that door and pushed cart up to a wall to hold it closed.  Don't think door is aliened  correctly & may be a manufactor's  problem.
