What are the spindle thingies on a staircase called again?
On the inside of a building those are called balusters, on the exterior of a building they are called spindles or pickets. You can call them whatever you want…I’ll understand you. For additional component name definitions and answers to specific questions to the construction of a staircase see: Anatomy of a Staircase Please feel free to call or email, with any questions you may have.
