BACKBONE DOUBLE

This system is particularly interesting for its flexibility, given by the ability to rotate along the vertical element of the base module, by the possibility of using rings that regulate the step tread as well as various other types of accessories that allow you to work with supports earth, wall or via live ropes.

The module

The module backbone double is composed of a cylindrical, central element which permits to adjust the risers between the steps thanks to spacer rings.

Furthermore, this cylindrical element carries, on its upper part, an Y-shaped element for the fixing of the glass tread, whereas the lower part can carry various supports for the wall and floor anchoring or for the stainless steel rope tightening.

The two horns shaping the Y exploits the principle of the inverted arch and carry at their ends two big cylinders necessary to support the glasses composing the treads.

Backbone Double, is the stairway system with double backbone that allows to create linear stairways, with or without landings, with railings both in stainless steel and glass. The benefits to have two or more "backbones" joined each other by horizontal elements are numerous:

• possibility of reaching larger widths
• to have structures with higher resistance
• to avoid (in some cases) supporting elements (floor or wall accessories)
• to increase the support points of the glass tread reducing its dimensions.
