Throwing batting practice from behind an L screen is standard for a reason, and this 7 by 7 foot version gives a pitcher a protected window at 83.86 by 37.8 by 83.86 inches with the cutout positioned for a right or left handed thrower. Iron pipe measuring 1.26 inches with a 1.2 mm wall holds the frame square against repeated line drives instead of folding after a hard shot. Pe netting absorbs the ball rather than rebounding it back at the pitcher. Ground stakes anchor the screen so it does not creep backward across a field during a session. At 22.7 lbs the screen carries in the included bag between fields, cages and backyards, which suits travel teams, school programs and parents throwing to a hitter at a local park. The screen measures 83.86 by 37.8 by 83.86 inches on 1.26 inch iron pipe. Netting, stakes and a carry bag ship together at 22.7 lbs.Suitable for ages 8 and up with adult supervision for minors. Warning: This screen reduces but does not eliminate the risk of injury from batted or thrown balls-always stay behind the protective netting, anchor the frame with the included ground stakes to prevent tipping, and do not climb or hang on the frame.
