Wall Flatness - SMART Board 4000 Series Installation Best Practices

CHAPTER 2
INSTALLING THE PRODUCT
NOTE
Refer to the SMART product's specifications for its weight.
In some situations, you may need to request an engineering analysis to determine if the wall can
support the SMART product.

Wall flatness

Although a wall might appear to be completely flat, it might have a degree of variation, depending
on how it is constructed. Installing the SMART product on a wall with a large variance can lead to
issues with the SMART product's touch system, and in extreme cases can damage the SMART
product. The area of the wall where you will mount the SMART product should be no more than
3/16" (5 mm) off plumb horizontally and vertically.
To evaluate the wall's flatness
1. Place an object that has a long flat edge of at least 3' (1 m), such as a meter stick or level,
across the wall where the SMART product will be mounted.
2. Look along the object to find places where there is a gap between the object's edge and the
wall's surface.
3. Measure any gaps to see if they exceed 3/16" (5 mm). If a gap is wider than 3/16" (5 mm), this
indicates the wall is not flat enough for mounting a SMART product.
4. Repeat steps 1–3, this time placing the object's flat edge diagonally across the wall in the
other direction (if you previously placed the object diagonally from the top-left to the
bottom-right, place the object from the top-right to the bottom-left).
TIP
Gaps located at the center of the object indicate a concave wall, while gaps located on
both ends of the object indicate a convex wall (consequently, the object may make a
"rocking" motion). Walls with a significant degree of concavity or convexity may require the
use of shims with the mounting hardware.
