holes and around the entire perimeter of the side of the section frames.
3. Lift the next section on the lower section row, Section 2, into position beside the first section
mounted. Install all lower display sections first.
4. Bolt the lower display sections together vertically. A detailed illustration of section bolting is
found in Drawing A-96848 in Appendix B. Adjust the section’s clip angles, if needed, and weld
to the upper and lower horizontal tubing.
5. If additional sections are to mount to the top of the bottom sections, remove the lift eye bolts from
the bottom sections and completely fill these holes with silicone. Apply a
3
/
16
-inch bead of
silicone around all interconnect holes and around the entire perimeter of the top of the bottom
section frames. Bring the first top section, Section 3, into position.
6. Bolt the upper section to the lower section. Adjust the upper section clip angles, if needed, and
weld to the upper and lower horizontal tubing. Apply a 3 /
16
-inch bead of silicone around all
interconnect holes and around the entire perimeter of the side of the section frame. Stack the next
upper display section (Section 4) onto the next lower section and bolt them together horizontally.
7. Bolt the top sections together vertically. Adjust the section’s clip angles, if needed, and weld to
the upper and lower horizontal tubing.
Height variation for any four-foot horizontal section must not exceed ¼-inch.
Display sections must bolt together vertically and horizontally.
After installation is complete, carefully inspect the display for any holes that may allow water to seep
into the display. Seal the any holes with silicone sealant.
If removing the eye bolts on the upper most sections (or the top of the display cabinet) from the
display, plug the holes with bolts and the rubber-sealing washer that came with the eye bolt.
2.5 Full Cabinet Display Mounting
Reference Drawing:
MTG Example, Full Matrix ................................................................... Drawing A-123964
The mounting procedure for a full cabinet display (also called a full matrix) varies from the procedure
used for a sectional display in a number of ways. The following is a general overview of the steps to
use while mounting a full cabinet display.
1. Inspect the display mounting structure before beginning the installation process.
2. Ensure that the structure will provide level and plumb frame for mounting the display. Height
variation in any 4-foot horizontal section must not exceed ¼ inch.
3. Also, check to see that the mounting frame will not give way at unsupported points after the
display mounts. If any problems are noted, take corrective action before mounting the display.
4. Bring the display cabinet into position and weld the upper and lower clip angles to the upper and
lower horizontal tubing as seen in Drawing A-123964 in Appendix B. Make sure the cabinet is
vertically plumb and horizontally level.
When applicable, project specific mounting details will be included in Appendix A. Call Daktronics
for additional mounting details and specifications. It is the responsibility of the installer to ensure the
installation will adequately meet local codes and standards. The mounting hardware and method is
also the responsibility of the installer. Be sure to maintain a minimum of ½-inch clearance between all
drain openings in the base of the sign and the mounting surface.
