5.2.6 All posts except brace posts shall be installed in a vertical position,
plumb and in line.
5.2.7 Terminal posts (Corner, End, Gate or Tension) shall be installed at the

and at changes in vertical and horizontal alignments exceeding 22½°
deflection angle.
5.2.8 All posts shall be equipped with moisture excluding top caps or
extension arms.
5.3 Top Rail
The top rail (41 mm O.D. pipe) for Saudi Aramco Security Fencing Type I and
Saudi Aramco Type II Fencing shall be continuous except over drive gates. One
expansion coupling shall be used for every 30 m of rail.
5.4 Brace Posts
Brace posts shall be attached to all Saudi Aramco Security Fencing Type I and
Saudi Aramco Type II line posts at a point 1500 mm above ground level and
extend downward toward the inside of the fence at 45° in a vertical plane which
is perpendicular to the plane of the fence. For Types III, IV, and V Fencing,
brace posts shall be installed on line posts at 90 m centers of fencing runs.
5.5 Chain Link Fence
5.5.1 The fencing fabric for Saudi Aramco Security Fencing Type I and Saudi

wires spaced at intervals not exceeding 300 mm. The tension wire shall
be attached to the line posts by tie wire wrapped around the post and
secured to the tension wire by 3 complete turns on each side of the post.
