Our New Tri-Fold Baseball Field Screen For Batting Practice, Portable Backstop Or Both Like our new oversize tri-fold baseball field screen? It's such a great and inexpensive idea that you won't believe that you have lived without it! For this price, you gotta have one for a bullpen backstop, a batting practice outfield screen, for your bucket tender or to easily create an extra batting practice area. Folds and rolls on and off your ballfield with a double wheel kit that we include. It can live outdoors with its weatherproof, waterproof UV stabilized net (yes, there are replacement nets available) but it will last even longer if stored indoors. This tri-fold baseball screen frame is made of 1-1\/2 inch powder-coated steel. Includes wheels for transport and ground anchor stakes for added stability in windy conditions. The overall size is 8 feet tall by 16 feet wide. The main panel is 8' x 8' and each wing panel is 8' x 4'. You can even fold one or both wings for your custom needs (do use the stabilizer ground stakes for safety sake)! You will find many drills to add to this unique baseball screen!
