CALCULATING THE
To determine the tread the formulas "A" and "B" must
be used according to both the staircase installation
type (fan-shaped or with landing) and their configuration
( "L" or "U") in addition to their width sizes. The
variables defining the JAZZ 22 - JAZZ25 models,
according to the staircase width, are reported on
page 8.
