Step 3
Identify the correct orientation of the post (refer
to Appendix A - Sentry Barrier™) and drive post
to the predetermined depth of 850 mm (790
mm protruding above ground) as stipulated in
Appendix A - Sentry Barrier™. The post must be
vertically aligned and within the tolerance level
stated in the Installation Tolerance section (page
16). The driving of the post should not incur
any damage to the post. If a post is damaged it
must be inspected and removed if considered
that the damage will affect the performance.
Step 4
Supporting the W-Beam in the desired location,
install the Sentry Barrier™ Bolt, Washer and
Nut. Once supported, the 8 Splice Bolts and
Nuts can be inserted into the W-Beam splice
joint. It is vital that each W-Beam must overlap
the prior W-Beam positioned downstream.
Failure to correctly overlap the W-Beam may
cause snagging, poor barrier performance or
risk injury or death to the driver of the errant
vehicle. Snug tighten all bolts once installed.
