Tie Down Vector Dynamics Foundation System for Wind Zones IBC 2009 - Manual (Page 14)

For metal piers, place the piers in the center of the Vector pads. Set the single 4x4 or two 2x4’s through the piers, and bumps against the
outside tension brackets. Inside tie brackets mount “upside down” as shown in drawing. Metal piers using the Vector System can only be
used on level ground sets.
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, part #59043 Vector system) 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.
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 or buckle 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, single section homes.
