S2W3W34N Winder Staircase – Left-Hand (With Handrail & Balustrade)

S2W3W34N – Left-Hand Double Winder Staircase with Handrail & Balustrade | Trade Range

The S2W3W34N Left-Hand winder staircase is a balanced Trade Range solution for projects where space is limited but a comfortable, well-proportioned stair is still required. Featuring two goings before the turn and four after, this layout provides a smoother transition through the winder section than tighter configurations.

This version turns to the left as you ascend and is supplied with a handrail and balustrade, making it suitable for open stairwells where edge protection and visual continuity are required.

Designed around your dimensions

Rather than relying on fixed sizes, the staircase is configured online to suit your build:

• Select your total floor-to-floor rise

• Choose the overall width over the strings

• The configurator calculates in real time:

  • Individual rise height

  • Stair going

  • Pitch angle

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

These values are displayed in a live Calculated Summary, allowing you to confirm proportions, footprint, and compliance guidance before placing your order.
