4.2 Installation of the rail system on the ladder
a) Place the safety rail on the centre and front side (the climber´s side)
of the ladder.
b) Place the safety rail so that the guide seat is situated on the left side.
c) Fix the safety rail to the ladder by means of the rung fi ttings.
d) Mount the rung fi ttings using hammerhead screws and self-locking
nuts, and following the instructions below.
i. For each rail section, mount a rung fi tting on the fi rst (lowest) rung of the
ladder.
ii. For each rail section, mount a rung fi tting on the last (highest) rung of
the ladder. This is also necessary even if the second or third last rung of the
ladder are mounted with a rung fi tting.
iii. For each rail section, mount a rung fi tting at least every third rung,
never leaving more than 2 consecutive rungs without a rung fi tting.
iv. For each rail section, mount at least 4 rung fi ttings to the ladder. When rail
section is connected to another rail section, the fi sh joint can be also considered
as a rung fi tting connection.
e) Use a fi sh-joint to join 2 consecutive safety rail sections.
f) Use 4 screws to mount each fi sh-joint.
g) Leave a gap between 2 consecutive safety rail sections of at least 1 mm
and maximum 4 mm.
h) Place the hammerhead screws with the indicator marks in an angle of 70°.
i) Tighten all the self-locking nuts to 8 Nm and ensure that they sit with the
70º angle.
