Protect pitchers as they practice throwing heaters, changeups and curve balls with this 8’ x 8’Baseball Pro L-Screen. Pitchers can focus on throwing strikes knowing they are fully covered by the screen’s oversize design. Whether it’s a soft hit toward the mound or a blazing fast line drive, the slip-over, pillowcase-style nylon netting and aluminum frame prevent the ball from hitting the pitcher and causing season-ending injuries. Frames are heavy wall schedule 40 aluminum 1.9” O.D. pipe. Permanent no flat tires roll easily across the field and allow quick setup before practice. Frame and wheel assemblies are welded for durability. 4” wide pneumatic tires are 10” in diameter. Weather treated nylon netting is #60 (3 mm), 1-3/4” mesh. Pillow case net design easily slips over frames and lacing is only required at the bottom to close the net. Aluminum screens are not recommended for inside a batting cage.
