Our installation guide refers to a number of terms that are specific to the staircase industry. Before you learn how to install a spiral staircase kit it is useful to understand stair kit terminology. Here is an explanation of the terms we use.
1) Balustrade:
The stair and landing guard rail containing the balusters and handrail.
2) Balusters or uprights:
Vertical posts that make up the stair or landing balustrade and support the handrails.
3) Handrail:

4) Rise:

6) Tread:
The horizontal part of the stair that people walk on.
7) Spacer ring:
