As it states in the main description area on this page, this product comes with everything EXCEPT the steel poles. Those, you can simply purchase at Home Depot or Lowes (we provide a link to both of those websites' pages for the poles).
We DO sell the complete cage that includes the poles but it's not the most economical way of paying for a batting cage. If you don't mind paying more than you have to, you can find the Cimarron 30x12x10 Complete #24 Batting Cage Net & Frame by clicking here.
