7.3.1. Barrier (fig.18)

1. Set up the fully equipped double bracket:
Each bracket is equipped with an anti-slip
pad (rep.1 fig.7) at the end to avoid any risk
of deterioration of the roof sealant. However,
it is recommended that the installer place it
gently on the ground and not step on it, as
this could lead to the deterioration of the roof

sealant. Space the brackets to a distance
equal to L1 (fig.18.1) apart at a minimum
distance of 50mm from the parapet.

2. Place a latch on each double bracket (rep.1,
fig. 18.2)
3. Insert the barrier into the holes in the double
bracket (fig. 18.3)
DANGER: the gearwheel must be
locked with the latch and be in contact
with the upper surface of the latch and
the upper surface of the double bracket tubes
(see detail B of Fig. 18.3).
4. Take a first counterweight with two hands
at the clearances and position it on the first
double bracket (rep. 2, fig. 18.4), taking care
to place the double bracket arm in the coun-
terweight groove provided to receive it.
IMPORTANT: Before placing the concrete
counterweight on the bracket, the installer
must ensure that the installation surface
Sm of the counterweight block (fig. 6) does not
have any sharp edges, deterioration or foreign
body to deteriorate the roof sealant of the roof.
NOTE: To place the counterweight (fig.
22), bring it against the hook of the dou-
ble bracket (step 1), swivel the weight (step 2),
and settle it (step3).
IMPORTANT: After placing the counter-
weight check that it is laying against the
whole installation area Sm (Fig. 6) and is

secured by the front and rear hooks of the dou-
ble bracket.

7.3.2. End barrier

The double bracket of the end barrier is ballast-
ed by 4 counterweights (fig. 14 position b).
A counterweight interface (rep. 1 fig. 20) should
be placed between each lower and upper coun-
terweight to ensure securing of the upper coun-
terweight in relation to the lower counterweight
(fig. 20)
