Example of a Double Section 28' x 72' Home
WIND ZONE I for Double Section Homes (High Pier Sets)
Using Vector Dynamics Foundation Systems
Soil Bearing Capacity: 1,000 PSF Minimum
Anchors Required: 30" with 2-4" helix anchors (#59095), 12" Stabilizer Plates (#59292)
& 1-1/4" frame tie with connector
Home Length Vector Systems Anchors Required Longitudinal
Required Per Side System (LSD)*
0 to 48' 2 2 2 (4 Struts)
49' to 71' 3 3 2 (4 Struts)
72' to 84' 4 4 2 (4 Struts)
85' to 90' 5 5 2 (4 Struts)
NOTES:
Pier height is measured from top of the Vector Pad to the
bottom of the I-beam. Vector Systems should be spaced
as symmetrically as possible along the length of the home.
Pier spacing must be consistent with home manufacturers
instruction and/or state requirements.
Maximum allowable working load for metal strut: 3150 lbs.
* One Longitudinal Vector System is made up of 2
struts, which can be used separately.
