Our Jump Walls are built with exterior grade plywood over a 4" x 4" pressure treated frame and are available in 12", 18", 24" and 30" heights. The plywood outer shell starts 1" above the bottom of the 4" x 4", so the plywood does not rest against the ground. They are painted inside and out with a primer and several finish coats for long-lasting protection against moisture. They have an oval hole cut in each side to use as a hand hold for easy moving. Jump Walls are sold in pairs and are available in three lengths to fit beneath 8', 10', and 12' wide jumps. Jump Walls are 12" from front to back. They are available in white, any standard solid color, or in faux brick, stacked stone or cobblestone patterns.
