With the external staircase Spino Zink Color you can reach storeys of up to 3055 mm. If this is not enough for your situation, you can consider installing a height extension. This consists of an additional step, a spindle tube and various parts to extend the railing. The steel parts are galvanised and can be powder-coated in black, anthracite or white to match the staircase. As with the stairs, there is a choice of diameters 120, 140, 160 and 180 cm. When purchasing, please ensure that the height extension matches your spiral staircase Spino Zink Color.

The additional spindle element including step has a flexible height of 190-235 mm. With one height extension, you can extend the Spino Zink Color external staircase to a maximum storey height of up to 3290 mm. If you install two additional steps, even storeys with a height of up to 3525 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.
