Take special care not to exceed the rated load of the eyebolts. Refer to ED-7244:
Eyebolts , to determine allowable loads and load angles for the lifting hardware.
ED7244 is located in Appendix B of this manual.
Avoid using other lifting methods. Cables and chains attached to the eyebolts and
directly to a center lifting point, as shown in the right-hand example in
Figure 4 , can
create a dangerous lateral force on the eyebolts and may cause the eyebolts to fail.

aluminum plate or steel nut plate, but exceeding load angles or weight limits could
cause the bolts to pull out or the scoreboard cabinet to buckle. In either
circumstance, the result would be serious damage to the scoreboard. If you must use
this method, ensure a minimum angle between the chain and scoreboard of at least
45°.
Note: Daktronics assumes no liability for scoreboard damage resulting from
incorrect setup or incorrect lifting methods.
Note: Eyebolts are intended for lifting only. Do not attempt to permanently support
the display by the eyebolts.
In installations in which an ad panel or some other scoreboard section may be added
to the base display, the lower scoreboard section is installed first and secured to the
support beams, and the upper section is then placed atop or above the lower section
and attached to the beams. There may be cables extending from the top of the lower
section. Guide these cables into the hole in the bottom of the upper section for later
connection.
If installers remove the lift eyebolts when the display is permanently mounted, plug
the holes with bolts and the rubber sealing washers that were removed with the
eyebolts. Apply silicone or another waterproof sealant to the eyebolt openings.
Inspect the top and sides of the display for any other holes or openings that may
allow moisture to enter the display, and plug and seal those openings as well. Failure
to do this could potentially cause wiring and corrosion problems in the future.

All of the tennis scoreboard models described in this manual mount to vertical
beams as part of an outdoor support structure. The display is secured to the structure
using clamps attached with Grade 5 hardware.
