AnemErgonics has received many inquiries regarding the use of its SMarT Foundation kits with TEC_WIND towers. These tilt-up, stackable towers are available in several heights, and we are told their tower base flanges use a 17-inch bolt circle.  We double checked our engineering calculations and revised our Foundation Drawing.pdf to accommodate 33', 45', 50', 55' and 60' towers with either 17" or 19" bolt circles.  Just make sure that when you order your SMarT Foundation kit you specify the correct bolt circle.  It's always best to check with the manufacturer to ensure compatibility.
