Bring new life to your Champion Sports Portable Collapsible Batting Tee (PROT) with the Replacement Stem and Top. This replacement kit includes both the ultra-flexible, helically wrapped rubber top and the aluminum telescoping stem that adjusts from 23" to 43" for customized practice sessions. The innovative cone design of the top provides valuable feedback on bat contact, while the adjustable stem tackles various swing heights. Just screw the threaded bottom of the stem onto your existing PROT base (not included) for a secure fit, and enjoy uninterrupted practice sessions. The convenient design allows for easy detachment of the stem for portability, making the PROT even more versatile for training anywhere.
