STRAINING POSTS
Straining posts are required at each end of the fence,
at each change of direction or when there is a large variation
in ground level. Straining posts should be positioned as follows:
(a) As terminal posts at the end of fencing runs
(b) As corner posts which are approx. at right angles
(c) As external corner posts for corners of 900 on
the inside of the fencing and as internal corner posts of 2700
on the inside of the fencing
(d) As intermediate straining posts, not exceeding
75m (81yds) apart, and at all deviations in the line of fencing
i.e at obtuse angles.
It is important to select the right type of post for the job
as the effectiveness of any fence depends on the correct support.
A wide choice of posts is available, including angle iron, wood,
concrete, tube and pylon.
FITTINGS FOR STRAINING
The illustration opposite shows the main components
used in straining chain link fencing:
(a) Eyebolt - for use with wood or concrete posts
(b) Ring Nut - for use with eyebolts for intermediate
two-way strainers
(c) Hook Bolt - for use with concrete intermediate
standards in place of hairpin staples
(d) Winding Brackets - for straining line wires
(e) Cleat - for fixing stretcher bars
(f) Stretcher bars

JOINING A ROLL OF FENCING
Remove a spiral from end of the roll to be joined
on. This is easily achieved by unknuckling the end of the first
spiral and winding the spiral upwards with an anti-clockwise
screwing motion until fully removed.
Bring together the end of one roll with the begining of the
next roll and unite them by twisting the loose spiral clockwise
through each link in screw form. When the spare spiral has been
screwed into position, the knuckles should be closed at the top
and bottom of the fence to complete the join.
SPLITTING A ROLL OF FENCING
First, unknuckle the top and bottom ends of the spiral
where split is required. Remove this spiral from the roll completely
by winding in an anti-clockwise direction.
NOTE - It is important that the end of the roll is joined
to
the beginning of the next.
