Stair Risers

Another product brought to you by Kerfkore Company.

Stair Risers are constructed with a hardboard face suitable for painting applications. It is also available with different veneer face options. The riser is designed for use on starting step applications where a bull nosed end is desired to provide a platform to mount the tread and banister railing.

Stair Risers are available in an 8" height with bendable end/ends to form the needed radius. The height can be reduced by edging on a table saw to a smaller width if needed. The product is shipped flat and by the use of a shaping rib can be bent and shaped into the desired form.

Stair Risers are designed to form a maximum diameter of 13" or it can be bent down to an 8" diameter if needed. This diameter is determined by the size of the bull nose needed for the particular application. The standard riser comes in an 8" wide (step height) so that it can be ripped down to match the needed step height.

Stair Risers are formed into the desired contour by the use of a curved forming rib. This rib should be machined to the correct shape and the riser then applied to this rib. Sometimes the use of a dado or rabbet is used to locate this rib for attachment. The rib should be glued, clamped and possibly pin nailed into place until dry.

Stair Risers are available in an economical paint grade and a variety of veneers including red oak, maple, pine and other specified veneers. Stair Risers are available in single or double nosed with different length options. A variety of substrates can be used as the core product such as plywood, particleboard and MDF.

The Stair Riser will consist of a rigid center section joined to the bendable Kerfkore on one or both ends. This allows for the riser to be shipped flat and then formed into the desired end radius by the use of a shaping rib. The product can create a diameter from 8" up to 13" without any telegraphing as found with other conventional bull nosed methods. Core materials of particleboard and plywood are available. Custom sizes made to customer specifications are available for reasonable quantities.

“The Kerfkore Foamkore product was the perfect material for the art piece I wanted to create. I needed something that had a physically and visually substantial structure, while being lightweight at the same time and this material had it all. The people at Kerfkore were extremely helpful and excited to help me achieve my vision, working with me to choose the product that would best suit my needs and to have the sheets cut to my particular specifications. Not only was the material's structure perfect, it did not require heavy duty jointing or extra reinforcements; I found that the joints in my sculptures adhered very well with a strong wood glue alone! Once my sculptures were complete, I was able to move them, place them and interact with them in the various environments I chose without any problem - instead of worrying about my sculptures breaking, I needed only to worry whether they would fit in my vehicle. I am really happy to have found and worked with this company ... they were a huge part of my success in this project.”
