9.   Rails  are  attached  to  the  Ezy-HC-Carriage  using  the 

M16x30mm carriage bolts. The post bolts are identified 
by the socket recess located in the head of the bolt. 
The bolts are tightened to snug tight using a 10mm 
hex. key.

10.  Rails are spliced together at every second post using 

M16x32mm mushroom head bolts and oversized nuts. 
There  are  12  bolts  required  per  splice  connection. A 
pinch bar may be used to assist in the alignment of 
splice holes. The use of a driving pin to elongate the 
slots is NOT to be used since this may cause tearing of 
the rail at the slot location. The bolts are tightened to 
snug tight.

11.   Rails  are  orientated  so  that  no  leading  edge  is 

presented to the traffic face as shown in Figure 15.

12.   It is recommended that posts be installed only a few 

metres ahead of rail assembly to ensure correct post 
spacing and alignment. On curves, the rails can be used 
as  a  template  and  laid  on  the  ground  to  determine 
post locations.

13.   The construction of Ezy-Guard HC shall form a smooth 

line  vertically  and  horizontally  when  viewed  along 
the line of the system, free from humps, sags or other 
irregularities.

14.   The Ezy-Guard HC components are to be free from splits, 

burrs or sharp edges after installation. Any minor damage 
is to be repaired in accordance with section 7.4.

15.   Any  disturbed  pavement  or  material  around  a  post 

shall be left dense, tight, and smooth so that resistance 
to water penetration is similar to that of the adjacent 
surface.

7.13   Installation Tolerances

 

The  tolerance  on  height  of  the  barrier  shall  be  plus  or 
minus 20mm.

 

The tolerance for the line of the barrier shall be plus or 
minus 20mm in plan view.

 

The tolerance for departure from the upright axis shall be 
plus or minus 15mm at the top of the barrier.

 

The tolerance on post spacing shall be plus or minus 25mm.

8.0  mAIntenAnce

It is recommended that annual inspections be performed to 
ensure the following;

 

The system is appropriately delineated;

 

Debris has not accumulated around the system that may 
impede the performance of the barrier or the trajectory of 
an impacting vehicle;

 

The  system  is  suitably  anchored  with  appropriate 
terminals and/or transitions. If the system is anchored with 
terminals, the cable assembly shall be taut and tensioned 
to its recommended value; and

 

All splice bolts and post bolts are snug tight.

9.0 product StorAGe

All  posts  and  rails  are  hot  dip  galvanized  in  accordance 
with  AS/NZS  4680.  It  is  important  that  stored  galvanized 
work is stacked so that each item is well ventilated and can 
adequately drain rainwater from its surfaces.

Poor storage can give rise to wet storage stain (white rust) 
which  is  caused  by  water  (rain  or  condensation)  in  badly 
drained or ventilated conditions. This can occur very quickly, 
particularly in warm, humid conditions.
