To make the outdoor staircase Spino Zink Smart suitable for storeys above 3055 mm, you can order the matching height extension. The height extension includes a spindle element, a stair tread and some parts for extending the railing. As with the staircase, the parts are made of galvanised steel. The steps are available in diameters of 120, 140, 160 and 180 cm. Please make sure you buy the height extension in the same size as your staircase.

With the additional step, you will achieve a height increase of 190-235 mm. In total, the Spino Zink Smart with one height extension has a maximum storey height of 3290 mm. If you fit two additional steps, you can climb storeys of up to 3525 mm.

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