NOTES:
* When a pier height at Vector locations exceeds 46”, an anchor must be used on the outside wall/beam at
that approximate location. Vector Systems should be spaced as symmetrical 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.
