Built with 13.5 gauge 1.5-inch diameter steel tubes, the Brute L-screen's frame withstands impact from line drives. Its durable construction makes it tough enough to endure continuous impact in batting cages. The extra-strength envelope-style net slides over the frame and attaches securely around the bottom tube with bungee cords. Made of 60-ply weatherized polyethylene, it provides top-notch protection through the elements. The Brute L-screen adapts to the pitcher--just reverse the screen's "L" shape to accommodate right or left-handers. Provide pitchers with security so they can focus on throwing perfect pitches. Pushpins make for a quick and easy assembly, so the Brute L-screen is ready to use in just a few minutes. Put it to the test right away as you perfect the pitching and hitting skills that make your team competitive. The Brute L-Screen's weight and superior strength make it ideal for use in batting cages. Weighing nearly 40 pounds, it's heavy-duty enough to stand strong and endure for seasons, even under continuous use. All CHAMPRO Brute screens include a 3-year frame warranty and a 1-year net warranty from the manufacturer covering defective parts and materials after registering on the website.
