The Batco Cage is 50% wider and 20% higher than standard tunnels. The larger size permits live batting practice to be thrown more comfortably. It is the only cage that you can use indoors and outdoors. Because of the shape and construction, the Batco Cage is not affected by wind; and with only two support bands, the Batco is almost self standing. When used indoors, it’s recommended to use a vinyl floor cover to protect the floor’s finish. Please specify if using indoor, outdoor or both. Indoor or outdoor feet are included but if using for both, there is an additional charge for another set of feet. Quality knotless #42 gauge netting has a tensile strength of 350 lbs. When folded, the Batco Cage is much easier to protect against vandalism. There are no cables to run indoors or a frame to build outdoors. The arcs are made of galvanized steel and weigh approximately 45 lbs. each. Written installation instructions are included along with a step-by-step installation video.
