Maximum Pier Height
Vector Dynamics Foundation Systems may be used on single section homes in Wind Zone I which require pier
heights (from surface of Vector pads to top of concrete or metal pier) not to exceed 50 inches under one or
both main rail(s). Note that a ground anchor must be used at each Vector system location where the pier height
exceeds 24 inches for single section homes. On multi-section homes in Wind Zone I, an anchor must be used at
each Vector System location with pier heights above 46” with the following exception: double section homes that
are 24’ wide, in Wind Zone I, have a maximum pier height without anchors of 38”. See page 16 for double
section home high pier set instructions.
