Step 3 - Post 1, Ground Strut and Soil Anchor
Place the roadside face of post 1 bottom anchor, 200mm towards the roadway to
compensate for the lack of blockout (Figure 7).
Post 1 bottom the Ground Strut and the Soil
Anchor are then placed parallel to the string line at this roadside offset position. Drive or place
the bottom of post 1 in the augured hole so that no more than 75mm (100mm max) protrudes
above ground level.
Use the Ground Strut as a template to place the Soil Anchor in the correct place. The Soil
Anchor can then be driven into place or placed in an augured hole and backfilled. The Ground
Strut should be level or lower at the anchor end than at the post 1 bottom end (Figure 8).
Place post 1 top in the post 1 bottom anchor ensuring that the post bolt notches are at the top
and facing the Soil Anchor (Figure 9). Use M16 x 200mm hex head bolt with nut and washers.
Do not over tighten bolt.

Step 4 - Hang Rail 3 and Cable Anchor Bracket
Rail 3 is installed like standard guardrail
with post 6 at the centre of the rail and
blockouts between the rail and post.
Place the Cable Anchor Bracket on the
back of the rail at the joint between rail 3
and rail 4 (post 7) refer to Figure 6. Figure
6A shows the bracket once X350 is fully
installed.
The two “boxes” on the cable bracket
should be on the impact head side of the
splice joint.
Attach rails to post with post bolt and
splice rail 3 to rail 4 with 8 standard splice
bolts.
