A base plate on the lower-most weight plate includes an extension beyond the plates to which a tent leg is secured. The weight plates include a tab matingly received in a track between rails on the cart to prevent shifting of the plates on the cart. The plates also include holes which are aligned when the plates are stacked so as to receive a post through the holes to maintain alignment of the stacked plates in use on the tent leg and during transport on the cart.
