Kerfkore Company is the manufacturer of a Stair Riser program that allows for the construction of the beginning step bull nosed riser. The 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.
