Tie Down Vector Dynamics Foundation System for Wind Zones lll - Manual (Page 9)

For metal piers, place the piers in the center of the Vector pads.
Set the single 4x4 or two 2x4’s through the piers, centered in the
U-bolts, so that the board(s) overhangs the pier base on each side
by about 2”. Outside Tension brackets attach the same, Inside tie
brackets mount “upside down” as shown in drawing. Metal piers
using the Vector Ground System can only be used on level ground
sets. Concrete pad sets would be set normal.
Conventional pier adjusters must be placed under beam with
upturned edge directed towards the outside of the home.
Pier spacing must be consistent with home manufacturers’ installation instructions and/or state requirements.
To cut lumber (2 - 2x4’s or 1 - 4x4 per, or 1 adjustable steel compression member) for the center compression
section, when using METAL PIER STANDS, measure center to center frame distance and add 16”. Optional Moisture
Termite Shield may be required in certain regions. ALL WOOD MUST BE PRESSURE TREATED, GROUND CONTACT RATED.
Tip: Pre-cut your lumber and mark as to brand or model of homes you will be installing. If frame widths are
the same, the pre-cut boards will also be the same length in each Vector set-up.
Metal Pier Ground Set Foundations
V-Drive System
for Rocky Soil Conditions
V-Drive anchors are used only in Zone I,
single section homes in areas where rocky
soil conditions do not allow helix style
anchors to be installed.
Vector Systems are set following the
general set up instructions provided. With
the V-Drive anchor, the short 2x4 boards
used with the outside tension brackets are discarded. In place of the short 2x4’s, a longer 2x4 is used as per the
diagram above. This 2x4 board should extend from the base of the Vector pier set to 5 inches from the side wall
of the home.
Place the V-Drive head over the end of the longer board. Using a heavy hammer or electric hammer gun, drive
the three V-Drive anchor rods through the V-Drive heads at an angle of approximately 45 degrees under the home.
The rods must come to a complete stop on the V-Drive head. Attach a strap with hook, buckle or swivel to the
frame and attach to the V-Drive head with a slotted bolt. Cut the strap end about 12 to 15 inches past the anchor
head to allow at least four or five wraps around the slotted bolt. Continue tightening strap until all slack is out and
strap is tight.
V-Drive Anchors are used only in
Zone I, for Single Section Homes
