Description

The height extension for the Portofino consists of an additional metal step, a spindle tube, some railing bars and various small parts for assembly. You must select the metal colour and the diameter of the height extension manually – please ensure that it matches your configured Portofino spiral staircase.

With each additional step, you can increase the Portofino by 210-231 mm. This means that with one height extension you can achieve a maximum storey height of 3234 mm. With two height extensions, even storeys with a maximum height of 3465 mm are no problem.

Please install a maximum of two height extensions per staircase! If three or more additional steps are installed, stability is no longer guaranteed.
