2.2. Fasten the risers to the rails
The risers are fastened to the rails with screws (M6x12, Torx 30), one in each rail.
Repeat the same procedure to fasten the seven risers.
1. Enter a screw into the top rail,
without tightening.
There is one screw for each
riser as shown in the illustration
to the left.
2. Hang a riser onto the screw.
The riser with a setback shall be
at center.
Check that the riser hangs on
the screw, and doesn’t rest on
the floor.
3. Fasten the riser to the middle
rail with a screw. Don't tighten
the screw now.
4. Fasten the riser to the bottom
rail with a screw. Don't tighten
the screw now.
