How to Build a Free-Standing Batting Cage
1. Netting: For outdoor use HDPE (high density polyethylene) nets are the best, as they don't absorb water, while Nylon nets are better for indoor use due to higher strength.

3. Frame Poles: Depending on the length of you cage you will need a specific amount of steel frame poles (standard 10' long) to be inserted in to the frame corners to construct a full batting cage.
