Frequently Asked Questions
1. What type of equipment is required to install the Sentry Barrier TL-4 ThrieBeam System?
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 ThrieBeam barrier as soon possible becaus
e 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 TL-4 ThrieBeam System?
Depending on circumstances at the site, installation and assembly of the system should take a three
person crew less than 15 mins per ThrieBeam 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 TL-4 ThrieBeam System 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 TL-4 ThrieBeam System be restored after impact?
Sentry Barrier TL-4 ThrieBeam System is easily repaired following an impact. Damaged posts can
be removed using a crowbar (or other appropriate equipment) and new posts installed before
replacement ThrieBeams and splice bolts are positioned.
The connection detail used between the post and the rail of the Sentry Barrier TL-4 ThrieBeam
System 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
(provided post is not damaged from an impact).
6. What maintenance does the Sentry Barrier TL-4 ThrieBeam System require?
The Sentry Barrier TL-4 ThrieBeam System is maintenance free. However, it is recommended that
all ThrieBeam barrier systems are checked after impacts to ensure that the integrity of the barrier is
maintained.
