S2W3W34N Winder Staircase – Left-Hand (No Handrails)

S2W3W34N – Left-Hand Double Winder Staircase (No Handrails) | Trade Range

The S2W3W34N Left-Hand winder staircase is designed for installations where space is limited but a balanced, comfortable winder layout is still required. With two goings before the turn and four after, this configuration provides a more gradual transition through the winder section compared to tighter layouts.

This version is Left-Hand turning (as you ascend the staircase) and is supplied without handrails, making it suitable for stairs positioned between walls or where balustrade components will be installed separately.

How the configurator works

Rather than fixed sizes, this staircase is configured online to suit your project:

• Select the total rise height

• Set the overall width over the strings

• The configurator calculates:

  • Individual rise

  • Stair going

  • Pitch angle

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

All key dimensions are shown in a live Calculated Summary, allowing you to confirm fit and proportions before placing your order.
