-
case at the beginning of the outer stair stringer.

Wooden stand constructions:
see 8.2.5
Stone or concrete walls:
Before mounting, you
must drill holes in the masonry with a masonry
drill bit. Mark the drill holes on the wall or drill the
plaster through the through hole in the stringer.
Remove the staircase, drill and then insert dowels
(matching the masonry) in the drill holes. Then align
the staircase with the wall in its final position.
