You must get replacement parts from the manufacturer regardless of whether your product is in or out of warranty.  They will need the model number of your item.  If you have the specific part number from the assembly manual, it would be helpful.  If your product is still under warranty, they will need the place and date of purchase as well as your receipt.  If you purchased from The Better Backyard, we can send you your receipt.Click here to see the manufacturers we support and their contact information for replacement parts, warranty issues and product support.
