Calculating Rail Length
Calculate the row lengths as follows:
1. Add module widths
2. Add width of mid clamps between modules
3. Add allowances for end clamps on ends of rail
Depending on the clamp selected for the system, the clearance values will dier slightly.
Grounding Mid Clamps UFO
Mid Clamp 0.25” 0.375”
End Clamp 1.5” 1.0”
For example, to mount ve modules that are each 40” wide (in portrait), the row length is calculated as follows:
Using Grounding Mid Clamps Using UFO
1. Add module widths 5 x 40” = 200”
2. Add width of mid clamps between modules 4 x 0.25” = 1” 4 x 0.375” = 1.5”
3. Add allowances for end clamps 2 x 1.5” = 3” 2 x 1” = 2
Total length of row 204” 203.5”
Two 17’ rails will be required to mount this row of ve modules.
IronRidge stock rail lengths: 11’, 14’, 17’. Custom lengths available via special order. Contact IronRidge Customer
