Description

This height extension allows you to add one extra tread to your Rondo Smart metal spiral staircase. The set includes a metal tread, a central column element and additional railing posts.

Match it to your staircase

The metal components have a powder-coated finish in black, grey or white. The height extension is available for staircase diameters of 120, 140 and 160 cm. Make sure the colour and size match your Rondo Smart when ordering.

One height extension adds between 190 and 235 mm. With one additional tread, a maximum floor-to-floor height of 3,290 mm is possible. With two height extensions, the staircase can reach up to 3,525 mm.

Important: Install no more than two height extensions. The required stability of the staircase cannot be guaranteed with three or more additional treads.
