This Architectural Drawing is AutoCAD 2d drawing of Building staircase railing details in AutoCAD, dwg files. The top surface of the handrail should be between 34 and 38 inches above the floor, or above the Nosing Line. Some installation guides suggest marking the height by measuring from the nosings of the steps. Although a baluster and a spindle are nearly identical, the word spindle is more frequently used since it is simpler to say and remember. While spindles are supported by a horizontal rail at the bottom that is joined to the posts, balusters typically rest on a foundation, which could be a step, floor, or deck. For more details and information download the drawing file.
