If the rst raiser measured is lower than 170 mm:
“A” values are calculated considering the rst raiser
of 170 mm.
If the rst raiser measure is very different from the
theoretic value used for the calculations (170 mm),
the “A” value must be recalculated according to the
following formula:
If the rst raiser measured is higher than 170 mm:
This table can be only used with alpha angle higher
than 20 degrees. Below 20°, it is necessary to carry
out a special study according to the type of staircase.
In case of angles lower than 20°, please contact Vimec
to receive soon the rail installation data.
