Rail Assemblies
Calculating Rail Length
Calculate total required mounting widths as follows:
Add module widths + .25” space between modules for mid clamps + 1.5” to each end for end clamping. This formula
will provide you with total width of rails. *If rail splices are needed, see page 7.
For example, to mount ve modules that are each 40” wide, the calculations are as follows:
• 5 x 40” = 200” (account for width of modules in portrait mode)
• 4 x .25” = 1” (account for width of mid-clamps between the ve modules)
• 2 x 1.5” = 3” (account for two end clamps on ends of rail)
• 200” + 1” + 3” = 204” (total length of one rail)
• Two 18’ rails will be required to mount these ve modules
*IronRidge stock rails lengths: 12’, 14’, 16’, and 18’. Custom lengths available via special order, contact

Calculating Panel Clamp Size
Module Clamp size depends on the module thickness. Use the table below to determine which Module Clamp will t
your projects module thickness. Reminder: Our Mid and End Clamps t both Standard (XRS) and Light (XRL) Rails.
