Our economical 55' Commercial Frame Kit includes elbows and feet (ground sleeves) made from 2" EMT steel, eye bolts, cables, turnbuckles (for both ends), clips (to hook the net to the cables), self-drilling screws, and angle supports made from 1 1/2" steel (to support the end arches). To complete the three-arch frame, you will need nine 10' lengths of 2" thin-walled EMT steel and four 10' lengths of 1.5" EMT steel which can be purchased at a local hardware store.
