Abstract: A metal railing comprises railing sections. Each railing section has an upper hollow handrail, and a lower hollow girder. A center post joins the handrail and the lower girder, and a plurality of filler posts extend between and into the upper handrail and lower girder on each side of the center post. The filler posts are interconnected within the upper handrail and the lower girder by long pins. The railing sections are movably connected to coupling posts or end posts. A cable extends through the upper handrail and is clamped at the coupler posts and at the end posts.
