Our Pro-Series screens use a heavy duty, extremely durable mesh material specifically designed to take the full impact of a real golf ball. The Pro-Series is made for those heavy hitters out there or people that want a impact screen that will hold up over time. While these are tested and designed for use with real golf balls, we suggest the use of soft balls to extend the life of the screen. There are pockets sewn into the top and bottom large enough for up to a 3/4" round pipe (electrical conduit) to fit into. The sides are hemmed and have heavy duty, non-tear grommets reinforced with nylon webbing. We have also added the nylon webbing as pictured to the pockets to increase the durability. The overall size of this screen is 96" X 96".
