Customer Questions & Answers

Does this include the extra piece of hand rail? If I add 2 can I put the stairs closer together but not add height?

Asked by: ER
The KARINA add riser kit comes complete with metal mounting structure, stair tread, and handrail to add an additional stair tread to the standard 11 stair treads in the standard kit. This is intended to be used to increase the height. If it is intended to be used to reduce the rise between treads, we would nee do know the "finished floor to finished floor" height of the planned installation to better advise as there is a minimum rise between treads that can be accomplished. Please contact our Customer Sales & Support team via our toll free telephone number at (888) 782-4758 and our team can assist with your specific application and provide the most helpful recommendation as relates to your planned installation.
