Each high-quality, American made seat plank is 10" wide with a ribbed no-slip surface and is anodized aluminum, so it will not rub off on clothing. The bench comes with Safety End Caps that have no sharp edges to snag clothing or skin. The sturdy legs are constructed of heavy duty commercial grade 2-3/8" O.D. galvanized steel. Legs mount directly to the surface (mounting hardware not included) for permanent installation if desired. This surface mount bench without back is 7.5' long.
