* Wind load areas are computed using different
formulas by different manufacturers. Instead of making a claim based on an unknown formula, we'll let the torque numbers speak for themselves. |
| ** Prices for competing rotators were pulled from retail websites in May 2003 and are in USD. |
AlfaSpid rotators are of a high
quality with Torque to spare
They are custom made to withstand
the harsh Canadian conditions.
