These guards are available in lengths of 8 feet, 10 feet, 12 feet, and 14 feet. They can be installed end-to end to meet your road width requirements. The H-15 and H-20 are also available in a 7 foot, 5-inch road length. Other options include a three rail clean out section (except on the U-80), end wings, and steel posts.
