3. Product description
The guard trac™ WP or guard trac™ WPS
system consists of an aluminium barrier with a
reinforced concrete counterweight, installed on
a flat roof, along an existing parapet to prevent
people from falling off.
The guard trac™ WP system (fig. 1) uses a
lower number of counterweights, compared
with the standard version, whilst the guard
trac™ WPS (fig. 2) is a reduced version that
allows to optimise the available free space on
the roof.
Installations should only be carried out in ar-
eas where a parapet of at least 150 mm high
is present. This parapet may form part of the
underlying structure or be installed on this sub-
sequently.
The guard trac™ WP or guard trac™ WPS
guardrail is fast and easy to install. One of the
main advantages of this equipment is that it can
be carried by hand in separate parts, and all
individual components have a weight of less
than 25 kg.
The guard trac™ WP or guard trac™ WPS
guardrail is self-standing and can therefore be
set up on a roof or terrace without drilling, which
reduces the risk of leaks and the need for addi-
tional maintenance. The guard trac™ guardrail
does not require any tools for installation.
The guard trac™ WP or guard trac™ WPS
guardrail can be used on roofs covered with
PVC or bonded bitumen, in compliance with
