The end rail system is comprised of a base member and an end rail member. The end rail member is designed to protect occupants when used on bleachers in gymnasiums and other spectator areas. The end rail member is comprised of vertical pickets and is designed to be installed and then removed after each use of the bleachers. The end rail member is fastened to the base member by using a set of thumb screws. The end rail is hinged through the vertical center so that it can then be folded and stored flat upon the deck of the bleachers for storage purposes.
