Product & Installation Manual: Sentry Barrier™
KEEPING
NZ SAFE
Installation Instructions
Before installing the Sentry Barrier™, ensure
that all components required for the system
are on site and have been identified. The
Sentry Barrier™ is an engineered safety device
made up of relatively small number of parts.
Please ensure familiarity with the makeup of
the system and the installation process prior
to commencing. If required, refer to the Bill of
Materials and Parts Identification sections in this
manual for more information.
Site Preparation
It is preferred that the Sentry Barrier™ be
installed on flat, level ground and tethered to an
approved terminal end or crash cushion. The
positioning of the Sentry Barrier™ commences
from the last post connected to the terminal
end or crash cushion, working upstream to
the prior terminal end or crash cushion. It is
recommended that a string line be used to
obtain the correct orientation and placement of
the posts and are aligned to the terminal end or
crash cushions.
Post Orientation with traffic flow direction
Ensure posts are correctly orientated in relation
to traffic flow direction by positioning the closed
side of the post towards oncoming traffic. Refer
to below.
BEFORE DRILLING OR EXCAVATION
ALWAYS ENSURE THAT THE AREA IS CLEAR
OF UNDERGROUND SERVICES.
Post driver machine - Impact head
Ensure a suitable post driver impact head that
has been designed to drive Sentry posts is
used in order to avoid damage to posts during
installation. Below are examples of suitably
designed impact heads. Contact CSP
®
for
assistance if required.
In cases where very hard ground conditions
are encountered, minor deformation may occur
near the top of the post. If it occurs, please
refer to Appendix I – ACCEPTABLE POST
DEFORMATION MEASURES & TOLERANCES,
to determine if the deformation is acceptable for
the continuation of installation.
