This unit is for in-ground use only and once installed has an adjustable height of 18"-23". Overall size 47”L x 24”W. Components are made of specially formulated recycled HDPE plastic based materials that will not rot, crack, peel or splinter. HDPE (High Density Polyethylene) is impervious to insects and bacteria; requires no maintenance; is non-toxic; and is unaffected by severe weather or direct sunlight. The easy to clean surfaces never require painting or sealing and are mold and mildew resistant. Paint, ink, and other substances will not permeate the plastic, which prevents permanent staining. Just clean with any standard cleaner or power wash for a bright crisp look for many years to come! Rust-proof Stainless Steel fasteners are used to insure long life and to maintain a beautiful appearance. The natural colors used on Kids' Station Outdoor products will add to rather than subtract from your natural playground environment's appearance. Avg Ship Time1-2 Weeks
