Protect the fans from stray balls with Baseball Backstops in any height and length you need. We'll make the backstop to fit your stadium or back yard. Our standard duty backstops are made with a #21 twine, but if you're backstop will be seeing heavier use we can make a heavy duty version out of #30 twine, or a premium version with #36 twine or professional strength version out of #42 twine. We also offer portable backstops and chain link backstops.
