The net is 40 feet long by 10 feet wide and 10 feet high. It is constructed using a rugged 21, 1 34' black polyester mesh treated for weather and UV resistance. It is trimmed with 14' black nylon rope for added strength and support where it is needed most. The installation kit includes the frame corners 4 and unions 6, white leg caps 10 for safe use indoors and quick link connectors 6 for suspending the net internally to the frame. All corners and unions are 1 12' welded steel tube with a durable powder coat finish for long wear. You purchase the net and installation kit, then simply pick up the frame materials at your local hardware supply store. For the 40' net, all you need is 23 10' pieces of 1 38' minimum 18 gauge fence top rail tubing. Please note that the frame shown is not included.
