2.4 Building the Wall, First Row
It is most important to make the first row straight. Do not put the screens on yet.
Laying the first row
1. Set the first row of Margays side by side without
the screens . Bolt them loosely together near the
bottom with the long side-to-side bolts, washers
and wingnuts.
2. Attach the screen supports to the front edge of the
first row. The screen support only mounts one
way and is used on the bottom row only. It pro-
vides a stop or rest for the bottom screens.
3. Check the straightness of this row. This first row
must be absolutely straight .
Do not use your eye alone to judge straightness. Use a
tightly stretched string or a very long level. It is ok if the
row is not level, as would be the case in a tilted wall, but
it must be straight.
4. Use shims under the Margays to make the row
straight vertically.
5. When the row is straight, tighten the bolts hold-
ing them together. Then check straightness one
more time .
6. Go to next section (page 16).
Why is straight so important?
All Planar display s that stack must have a straight
first row. If the first row is not straight, the arrange-
ment gets worse as the wall goes up, and the screens
won’t align properly.
Margay is a little more critical of straightness,
because its screens have almost no mullions.
The mullion is the outside border of the screen. In
most Planar products this is a narrow edge of metal
that holds the screen in place. In Margay the mullion
is a thin piece of tape.
The advantage of this “mullion-less” screen is that
the finished wall will have almost no black lines
between images on the screens.
