Railing pattern Design Cad blocks in AutoCAD, dwg file.
<p>This Architectural Drawing is AutoCAD 2d drawing of Railing pattern Design Cad blocks in AutoCAD, dwg file. The IRC requires that the space between your balusters or boards must be <strong>less than 4″</strong>. To be on the safe side, I recommend using 3.5″ for your spacing. The last thing you want is to build your railing, and have an inspector not pass it because he's able to fit a 4″ object through your railing.</p>
