At Stairs and Stairways, you can purchase directly one of the many stock or custom Poplar wood railing profiles listed in the Buy-Now Section of our website. Poplar hand railings vary in size and shape to fit your personal design needs and design function. The profiles 6010 and 6210 profiles are the most popular, but there are others available to fit the needs of each individual staircase. Poplar handrails that have plows for square-top balusters have a tendency to be on the wider side and ADA rails lean toward the narrower sizing. At Stairs and Stairways you will be provided with professional full-time stair designers to certify that your orders are correct.
