Customer Questions & Answers

Additional Height

Hi, my floor to floor height is 10-8" so if I buy the standard kit plus one extra tread, will the handrail be long enough?
Asked by: Tim
Thank you for your interest in the Phoenix spiral staircase kit from ARKE. For the installation height noted of 10' 8", the standard kit (adjustable to the height of 10') PLUS 1 (one) additional stair tread kit will allow you to complete the installation. You will not need any additional handrail or center pole extension to complete the installation. Should you have further questions, please feel free to contact our Customer Sales & Support team via our toll-free telephone number at (888) 782-4758. Best regards.
