This tent frame will create a 15' x 40' structure to receive your existing canopy. The frame is made from 2" anodized marine aluminum tubing for superior strength, and the parts attach together easily using pins. All the corners, center crown, and side fittings are made from welded steel. The package contains both the frame and all the stakes necessary to secure the structure during windy conditions. A 1-year manufacturer's warranty applies to this item. Note that the canopy is not included in this purchase.
