The CHAMPRO Pitcher’s Safety Steel Frame L-Screen provides the protection pitchers need for on-field play and practice. Make sure pitchers can stay in the moment and focus on improving their skills. Built with 18 gauge 1.5-inch diameter steel tubes and a weatherized 45-ply PE net . this screen remains tough and sturdy as it stands guard through intense practices . so pitchers can focus on perfecting form and technique as they prepare for the next game. This reversible L-Screen screen adapts to both right-handed and left-handed pitchers–just turn the screen around to switch between right and left-handers. It’s also easy to assemble. Use the push-pins to lock the interlocking steel tubes in place . then slide the net over the frame and secure it to the bottom tube with bungee straps. This heavy-duty screen weighs about 37 pounds . making it light enough to move around the yard or on and off the field once assembled. Attach a CHAMPRO field screen wheel kit (not included) for even greater ease of mobility. Not recommended for batting cages–check out the CHAMPRO Brute line for extra-tough batting cage screens.
