CURVED VIDEO WALL GUIDELINES
The ConnexSys™ LVSXU is UL listed for use in certain curved video wall applications – but how do you know
if your install fits the criteria? Use this guide to determine if ConnexSys is a good match for your curved wall
installation. For comprehensive guidelines on mounting the LVSXU please reference the installation manual.
Strut Channel & Curve Radius Requirements
ConnexSys is compatible with curved walls built in a radius of 200"(5.08 m) or greater. The strut channel
material being used should also follow the guidelines listed in the chart below
Calculating the Wall Radius
1. Place a rigid, flat stick or strut channel (at least 3 ft or 1 m long – preferably longer) against the curved
wall as shown in the example below. Do NOT bend the stick or strut.
2. Measure the largest gap between the stick or strut and the wall.
3. Calculate the radius with the following equation:
Gap/2 + (Length/8 x Length/Gap) = Radius
Example
Stick/Strut Length: 48” (121.9 cm)
Gap: 0.375” (9.5 mm)
0.375/2 + (48/8 x 48/0.375) = 768” (19.5 m) Radius
STRUT CHANNEL MATERIAL
Aluminum Steel
Minimum Wall Radius Greater than 200"(5.08 m) Greater than 400"(10.16 m)
Minimum Yield Strength 30 ksi (207 MPa) 33 ksi (230 MPa)
Material Thickness 0.078” (2 mm) 14 ga – 0.075"(2 mm) or 12 ga – 0.104"(2.5 mm)
Strut Channel Depth 13/16"(21 mm) or 7/8"(22 mm)
Flange Length 1/4 - 9/32"(6-7 mm)

Curved Video Walls on Flat Walls
ConnexSys™can also be used to create curved
video walls when mounted on flat walls. Things
to note when designing a curved video wall on a
flat surface:
• The maximum angle a mount can make from vertical is 5.5 degrees
• Two or more mounts placed side-by-side can create a maximum angle of 11 degrees
• All other criteria listed in the above “Strut Channel Requirements” still apply
Allowing Space for Mount Adjustability
To retain the maximum amount of adjustability for video wall alignment, you will need to plan to use more than
the minimum depth capabilities of the ConnexSys mount. As a rule of thumb, assume the mount is 4.5" (11.4 cm)
deep. Then take the longest dimension of the video wall and multiply by the relevant depth adjustment factor to
determine the minimum mount depth needed for your installation.
Wall Radius Depth Adjustment Factor
Radius > 500" (12.7 m) .0025" per inch (2.5 mm per meter)
200" (5.08 m) < Radius < 500” (12.7 m) .00312" per inch (3.12 mm per meter)
Example
In the example shown on right, you should install under the
assumption that the depth will be 4.86” (12.36 cm).
Because 146.7" is greater than 113.2", we use 146.7".
4.5” + (146.7” x .0025”) = 4.86”
