Customer Questions & Answers

How many kits would I need for an 8ft stairs in a cabin loft?

What would this cost?
Asked by: Deb
You would not buy the individual Add Risers for your project. You would purchase the standard Eureka spiral staircase kit (#K21006) PLUS one 32" center pole (#K00000). You would use the 32" center pole in replacement of one of the 49" center poles in the standard kit. This combination would allow you to complete your installation to the noted 8 height. If you have additional questions, please contact our Customer Sales & Support team via our toll free telephone number at (888) 782-4758 and our team will be happy to assist and answer any further questions. Thank you for your inquiry and interest in an ARKE staircase kit for your planned project.
