NOTES:
*No anchors required for pier heights up to 46” for 28’-36’ wide,
38” for 24’ wide. When a pier height at the Vector location is
exceeded, an anchor must be installed outside that location, and
1 longitudinal Vector System added per house.
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.

One Longitudinal Vector System is made up of 2 struts, which
can be used separately.
