4 of 10 feet long 1 inch diameter PVC pipes. 2 of 90° elbows. 4 of the tee joints. All of the feet in this picture are 2 feet long. The top rung is interchangeable with 10 feet long 1/2 diameter PEX pipe to make a rounded ballon frame. Use duck tape to secure for the rounded frame. This frame is easy to setup and take apart for storage. There will be extra pieces with these cut lengths which is fine for interchangeability.
