Railing
A railing attached to a wall must be at least 1¼ inch and no more than 2 inches thick. The support brackets must hold the railing at a distance of at least 1½ inches from the wall and project a maximum of 3½ inches from the wall. The surface of a railing must be smooth, with no sharp corners.
Stairs should have a handrail on at least one side if they are less than 1 metre wide, or both sides if they are wider.
