BALUSTRADE (120 CM)
RISER BAR Allows to reduce the space between treads to prevent children from falling.
HOW TO CHOOSE THE STAIRCASE Through the following configurations you can determine the direction of rotation and the starting point of the staircase for the respective diameters: 118, 128, 138, 148 and 158 cm. The floor opening must be at least 5 cm larger than the staircase diameter.
Ø 118 α = 32,6°
Ø 128 α = 32,2°
Ø 138 α = 29,6°
Ø 148 α = 29,42°
Ø 158 α = 27,4°
