Mechanical Installation

Do NOT attempt to lift the cabinet if the angle is
less than 45°. Exceeding load angles or weight limits
could cause the bolts in the cabinet to buckle,
resulting in serious damage to the equipment or injury
to personnel. Also, loads should be applied directly in
the plane of the eyebolt as shown in Figure 4 .
Note: Daktronics assumes no liability for damages
resulting from incorrect setup or lifting
methods. Eyebolts are intended for lifting
only. Do not attempt to permanently support
the cabinet by the eyebolts or eyebolt holes.
In typical multi-section installations, the lowest display
section is installed first and secured to the support
beams. The upper sections are then placed atop
or above the lower sections and attached to the
beams.
If installers remove the eyebolts, plug the holes with bolts and the rubber washers that
are used with the eyebolts. Apply silicone or another waterproof sealant to the eyebolt
openings. Also inspect the top and sides of the display for any other holes that may allow
moisture to enter the display, then plug and seal those openings.
Extruded Cabinet Mounting
Four standard mounting methods are available for displays with extruded cabinets.
Each method requires spring nuts to be inserted into the rear channels of the cabinet.
Note: Do not use lubrication on any mounting hardware or the warranty will be void!
1� Insert spring nuts into the top and bottom cabinet channels. Twist the spring nuts until
they are perpendicular to the channel ( Figure 5 ).
2� Measure the beam spacing and position a spring nut on either side of the beams.
Each display section requires four spring nuts per beam (two at the top and two at
the bottom).

Once the spring nuts are in place, refer to the appropriate section that follows for the
type of mounting hardware provided with the display.
