COOL-it Custom Fan Drawing and Instructions
The inside of roll cage bar measurements are what is needed 15" apart from where the fans will mount. Subtract 1/2" from your each of your two measurements because 1/4" clearance is required on each side of the fans. See example below and or CLICK HERE for drawing example.
Example Roll Cage is 42" wide at the front of the fan mount location and 41.5" wide at the back of the fan mount location. Front and back measurements are taken 15" apart. Example measurement calculations are front (42 - .5 = 41.5") and back (41.5 - .5 = 41"). Please call if this does not make sense. 801 367 1395
