S1W3W35N Winder Staircase – Right-Hand (With Handrails)

S1W3W35N – Right-Hand Winder Staircase with Handrail | Trade Range

The S1W3W35N Right-Hand winder staircase is designed for compact floor plans where a straight flight would exceed the available footprint. Turning to the right as you ascend, this Trade Range kit includes a factory-prepared handrail, making it suitable for domestic installations that require a complete, compliant stair solution without additional joinery work.

Rather than relying on fixed sizes, this staircase is configured online to suit your exact floor-to-floor height and width requirements, with all key dimensions calculated in real time.

How it works

• Select your total rise within the supported range

• Set the overall width over the strings

• The system calculates:

  • Individual rise

  • Stair going

  • Pitch angle

  • Entry length, centre run (Run B), and exit length

This allows you to assess fit, proportions, and compliance before placing your order, reducing uncertainty on site.
