Abstract: A support bracket for protective railing may be adjustably positioned on a wall or other surface. The bracket is constructed such that when the bracket is loosely assembled, the placement of a rail segment on the bracket may be adjusted as desired within a limited range in one or more directions. After the placement of the rail segment has been adjusted, the component parts of the bracket are tightened to fix the rail segment in place. When assembled, the bracket forms a sealed unit with a smooth exterior that has a minimal tendency to collect dust, dirt and bacteria and that is easy to clean.
