Our Professional Screens are larger in size to accommodate collegiate and professional players. Frames are heavy wall schedule 40 aluminum pipe that is 1-5/8” diameter. Frame and wheel assemblies are welded for durability. Permanent 8” semi-pneumatic wheels for easy transport. Netting is #36 nylon weather treated, 1-3/4” mesh. Netting is fabricated in pillow case designs that slip over frames. Lacing is only required at the bottom to close the net. (Professional Screens are shipped motor freight).
