Craftsmans Pine S9W3N Left-Hand Top Winder Flight of Stairs (No Handrails)

A durable left-hand top winder flight of stairs in solid Craftsmans Pine

This left-hand top winder flight of stairs (S9W3N) is built for long service life and straightforward installation. The plan uses a kite winder staircase at the top to turn the run neatly onto the landing without stealing extra floor space—ideal where a straight flight won’t fit.
