Product Overview

The Civik interior spiral staircase model is available in 3 diameters - 3 ft. 11 1/4 in., 4 ft. 7 1/8 in., and 5 ft. 3 in. It is available in 3 colors - black, white, and grey - powder coat finish - ready to install - clockwise as well as counter-clockwise. The treads are made of solid steel, with black durable non-slip PVC tread covers. The handrails are made with a flexible aluminum core with a black covered grip. The standard Civik staircase kit is adjustable in height from 8 ft. 3 1/4 in. to 10 ft. 1/8 in. and with additional components, can be extended to a maximum height of 12 ft. 4 in. or to a minimum of 6 ft. 10 5/8 in. The standard kit with 12 treads and the landing installs with a 360° turn. By adding or subtracting treads the rotation will change by approx. 30° per tread. Additional riser kits can be purchased separately. To allow for proper installation and full clearance, the finished (round, square or mezzanine) opening for the installation of the spiral staircase must be at least 2 in. greater than the diameter of the staircase kit. To complete your project a balcony rail kit is available. Riser bars are available in a set of 12 to close off the back of the treads (this way a 4 in. sphere will not pass through). Each Civik staircase kit is shipped complete with detailed assembly instructions to assist in your installation.

The directions could have been a bit more clear. I tried looking at the generic video on their site and it was no help. A good video would be very helpful.
