Installation guide steps
1. With the required number of concrete blocks in place next to each other. If using the pin anchor
on the V28 for transportation, it must be thoroughly examined to detect
wear/damage/security concern before and after each lift.
2. Use all correct fixings and components to secure the blocks next to each other (M24 x 320)
3. Figure I and Figure J show the two ways of starting the fence panel assembly. This will be
depending on your site-specific risk assessment.
4. Refer to Fig A and B, place the posts on the two V28 fixing holes. Secure the post base by using
two M24 x 50 bolts. Do not tighten any bolts at this stage. (Use the dedicated V28 spanner if
supplied as in A1)
5. Repeat the above process for the desired length of barrier and required fences, Fig C.
6. Refer to Fig D, two-person operation: Starting from one side, lift one fence panel and locate it
under the upper U-Post clamp of the post, Fig E. Do not tighten any bolts at this stage.
7. Secure the fence panel to the bracket of the post using 1 x U-bolt M10, Fig F. Do not tighten any
bolts at this stage. Make sure to locate the U-bolt through the mesh and that both pin legs are
slotted in the bracket holes, Fig G & H.
8. Repeat the process in Step 7 for the desired number of fence panels. Do not tighten any bolts at
this stage.
9. Once all the fences with the post are in place, push them together to adjust and close any gaps
present. Tighten all bolts on the system using the appropriate tools.
10. Carry a final check on all fences, posts, plates, bolts, nuts, and blocks, Fig I/J.
The final decision regarding the installation of the system remains with the site manager.
Note 1: The system offers a very small degree of elevation and inclination flexibility. The overlap takes
care of the longitudinal change and the slotted post base allows for sideways direction change.
Note 2: Customers must not add signs or banners to the fencing as this will increase the wind resistance
of the fencing.
Maintenance
Carry daily checks on the complete barrier system including blocks, fence and security fixings. Check
that all fixings are tightened and secured.
The system must not be modified
