Stringers at both sides tab
Used to determine the dimensions of the steps if you have selected the "strings both sides" stair design.
| Setting | Description |
|---|---|
| Step width | Input the depth of the step here. |
| Angular extension | The outer edge of the step is bigger than the inner edge by this value, creating an angular stair. |
| b,c,d | Spacing dimensions for the mounting holes for the steps. b is the distance between the holes of the upper edge of the step, c is the height of the step mountings, d is the hole spacing of both mounting holes. |
| Hole spacing | The center distance of the mounting holes of the steps. |
| Hole diameter | The hole diameter of the step mounting holes. |
| Oblong hole axis | The distance of the axis of the back oblong holes of the stairs. |
| Indent | The offset of the stair steps from the front edge of the step backwards. Negative values push the step forwards. |
| Bent outer edge | The outer edge of the step is designed as a bent edge and adapted to the radius of the spiral. Otherwise this is designed as a straight edge (string of the arch). |
