For the most effective baseball practice, the FORTRESS baseball sock net screen is designed to catch & collect your baseballs so you can perfect your baseball pitching & batting skills efficiently. Wide steel feet provide a sturdy base to withstand high impact balls & blustering winds, whilst #42 weight baseball netting ensures your baseball protective screen stands the test of time. For enhanced durability, the extra-strength frame & netting are treated for weather protection – UV stabilised, rot-proof & rust protected. The double-layered netting increases player safety, with a pillowcase-style net design that simply slips over the frame of your baseball screen & clips into place.
