Product & Installation Manual: Sentry Barrier™
KEEPING
NZ SAFE
Frequently Asked Questions
1. What type of equipment is required to install
the Sentry Barrier™?
Standard tools required include a wrench,
measuring tape, string line and machinery
suitable for drilling or compacting the post
into soil.
2. Does your company provide spare parts?
What is the lead-time for supply?
It is important to fix a damaged W-Beam
barrier as soon possible because it most
probably won’t perform as designed when
damaged. For this reason it is recommended
that spares are held by Maintenance
Contractors. The lead time for parts will
generally be next day delivery or collection
from one of our distribution centres.
3. On average, how long does it take to install
the Sentry Barrier™?
Depending on circumstances at the site,
installation and assembly of the system
should take a three person crew less than 15
mins per W-Beam panel (4.0 m length) when
using automatic post driving equipment.
Installation time will vary depending on
ground conditions when hand digging and
re-compacting posts.
4. What about vandalism, can the Sentry
Barrier™ be damaged easily?
No, once the system has been fully installed
it becomes a rigid system unlikely to be
damaged or weaken the performance of the
system.
5. How easily can the Sentry Barrier™ be
restored after impact?
Sentry Barrier™ is easily repaired following
an impact. Damaged posts can be removed
using a crow bar and new posts installed
before replacement W-Beams and splice
bolts are positioned.
The connection detail used between the
post and the rail of the Sentry Barrier™ is
designed to limit damage to the post outside
of the immediate zone of impact. When the
connection is damaged, the washer detail
can be easily replaced without needing to
replace the post.
6. What maintenance does the Sentry Barrier™
require?
The Sentry Barrier™ is maintenance free.
However it is recommended that all W-Beam
barrier systems are checked after impacts
to ensure that the integrity of the barrier is
maintained.
