  • Module Clamp size depends on the module thickness. Use the table below to determine which Module Clamp will fit your module's thickness.
  • IronRidge Mid and End Clamps fit all XR Rails
  • Mid clamps are used when top mounting solar modules to the top slots of the rails - they are not dependent upon the solar module's mounting holes.
  • The T-Bolt design allows for easier installation because the installer can insert the mid clamp as each PV module is installed. With hex bolt mid clamps, the installer must slide the mid clamps onto the rail prior to installing the PV modules and space them according to the module width.
  • T-Bolt mid clamps create a spacing of .25" between modules thus maximizing the total number of modules per set of rails.
  • Available in clear or black anodized finish.

    Here are some tips from the altE staff

    • True solar south and magnetic south vary depending on where you are on the globe. Be sure to orient your solar panel mounts as close to solar south as possible. To find out how far off your magnetic south is from solar south check out <a href="http://www.ngdc.noaa.gov/geomagmodels/struts/calcDeclination" target="_blank">NOAA's handy calculator</a>.
