The Snowboarding railbox serves as a fixture in freestyle parks at mountain resorts around the world. Comprised of a wood box with one or more metal railings for sliding on and performing tricks, snowboarding railboxes vary in size and skill level. The railboxes sit on the surface of the snow and are held in place by their own weight. These instructions will explain how to make a railbox that is 3 x 3 x 6 feet long and that has one metal rail slide. The dimensions can be adjusted to make railboxes of different sizes and shapes.
