    Is the direction of the turn determined by looking up or down the staircase?

    Hi Donna,
    The direction of the turn is determined by standing at the bottom of the stairs and looking up. If you have any other questions please let us know.

    I have a four tread right hand curved winder. 22.5 degree “wedges” with a 52″ outer radius and a 10″ inner radius. Can you folks make these?

    We can absolutely make you custom treads to those specifications. What we’d ask is for precise drawings, or for you to mail us a template. We will then engineer the treads, and send you drawings to confirm before manufacturing.
    Please let us know if you have any more questions. And feel free to email the drawing to
