For a grand entrance, look no further… craftsmanship at its best, designed just for you.

Key Features

  • Starting Step
  • Large Rounded End(s)
  • Stain-Grade
  • Customizable

Rounded End

Each side of the 8650 Starting Step that does not attach to a wall requires a decorative Rounded End to accommodate a newel.There are three configurations available: Left, Right, and Double. NOTE: If both sides of the stair treads fit against a wall, you do not need this style of starting step.

To determine if a Left or Right Rounded End is required, stand at the bottom of the stairway and look up. If the right side is exposed, then you need a Right Rounded End. If the left side is exposed, then you need a Left Rounded End.

Double Rounded End starting steps are needed when both sides of the starting step are exposed. This style requires a special measurement called the “throat cut”, which you will need to provide when you place your order. To find the throat cut, measure the length between the inside of the Left and Right Rounded End. Each Rounded End adds 10 ⅜” per side.

Additional Style Options

  • Distressed Detailing
  • Hand Scraped Textures
  • Paint Grade Risers
  • Molding

Note, wood products may have varying amounts of staves due to the varying thicknesses of lumber that comes in each bunk and the width of the product.

Clear Finish & Stain Information

StairSupplies™ offers several premium stain and finish options for our products, depending on the product’s use. For Starting Steps, we offer both clear finishes and stains. Select a clear finish if you want to draw out the natural beauty and colors of the wood. If you prefer deeper, richer tones, our custom-mixed stains are the ideal choice for your Starting Steps.

All tread materials and products that are used underfoot are finished with a Conversion Varnish. Strong and resilient, this varnish is standard in the hardwood flooring industry. Our team of experts apply this specialty product onto each stair tread using a spray applicator for even, flawless coverage to protect your treads against heavy wear and tear.

Wood Grain & Color Variation

At StairSupplies™ we believe that natural wood colors and visual textures add character to our products. With that in mind, we strive to match the grain and color of all of our wood products as closely as possible. However, due to the natural variation of wood products, there may be instances in which a perfect grain and color match is not possible. By ordering from StairSupplies™, you acknowledge that you are receiving a uniquely crafted product and there may be some variation in the grain and color of your wood products.

    Whats the overall length for the 42″ version of this product?

    5 years 10 months ago

    Hi Sean,

    The 42″ measurement refers to the throat cut of this product – the width between the returns. Each rounded return adds 10-3/8″ of overall width. So for a left- or right-return 8650 starting step at 42″, the overall width would be 52-3/8″. Or, for a double return, you’d be looking at 62-3/4″ of overall width. Should you have any additional questions, please give our team a call at 1 (866) 226-6536.

    Is this overall width the width at floor level (width of the riser), or the width of the tread?

    5 years 1 month ago

    Thanks for the question Jessica.

    The width you order (i.e. 36″) is the width of the throat cut (which is the cutout you see in the photo). The returns then have a diameter of 17 1/2″ so if you add the width of the throat cut to 17 1/2″ for a single return or 34″ if you have a double return, you should get the overall width at the top.
