Need to install a center grab bar for steps that are about 6' wide. The owners want a bar up the center. Does anyone have a company for this? I would like it to be Stainless without infill, just a bar that has an upright at the bottom and top and the grab to be between 34 and 38 inches in height. Also it will probably be attached with pour stone, because the top and bottom are cement embedded pavers.
