4. INSTALLING HEADER ASSEMBLY
1
Place your hop ups / step ladders and one guide runner
each side of the opening.
2
With one person each end, lift the header assembly by the
header plate up and then guide the locating stem at each
end into the hollow section of guide runners. If there is
not enough room to simply drop the locating stem in, you
can angle the header plate
(fig.4.1)
. Make sure to insert
the stem fully into the guide runner
(fig.4.2)
.
3
Lift the whole unit flush into place and check that the top
box and guide runners are plumb, level and square.
4
Drill your fixing through the top hole in the guide runners
and secure into place
(fig.4.3)
.
5
Check the case and guide runners are still level and square,
then proceed to drill your remaining fixings, remembering
to check the guide runners are square and plumb after each
fixing.
6
Once the guide runners are fixed you will need to secure
the top box with 2 fixings each side. This is best done by
drilling through the end flanges of the header plate for a
behind fix, or sideways through the header plate itself if a
between fixing
(fig.4.4)
, PLEASE NOTE: The large cut outs
in header plate are only for use with larger fixings e.g.
shield anchor or coach screw.
7
Check to make sure all fixings have not caused the front
fascia to be pulled in, as this will rub against the slats
causing damage and scratching to the face.
