10 Mechanical Installation
Welding to Horizontals
Steel clip angles are first bolted to the back of each scoreboard section. These clip angles are
then welded on three sides to a horizontal tube, which itself has been welded to the support
beams. Refer to the sections below for suggested horizontal tube spacing.
Models BA-2001 & BA-2008
Figure 7 shows the spacing of the horizontal tubes for BA-2001
and BA-2008 single-section scoreboards. The horizontal tubing
must have a vertical dimension (height) of 4" (102 mm).
The bottom of the first horizontal tube is level with the bottom of
the scoreboard and is considered the zero mark for measuring
the other horizontal tube. The second horizontal tube is at 84"
(2134 mm), including the height of the tube, and will be flush
with the top of the scoreboard. Spacing may vary depending on
the installation. Refer to any project-specific shop drawings for
exact tube and clip angle spacing.
Models BA-2002 & BA-2009
Figure 8 shows the spacing of the horizontal tubes for
BA-2002 and BA-2009 multi-section scoreboards.
The horizontal tubing must have a vertical dimension
(height) of 4" (102 mm). The bottom of the first horizontal
tube is level with the bottom of the scoreboard and is
considered the zero mark for measuring the other two
horizontal tubes. The middle horizontal tube is at 66.2"
(1681 mm), including the height of the tube. The top
horizontal tube is at 112.4" (2855 mm), including the
height of the tube, and will be flush with the top of the
scoreboard. Spacing may vary depending on the
installation. Refer to any project-specific shop drawings
for exact tube and clip angle spacing.
