Vector Dynamics System
for Concrete Applications
Instructions
These instructions are an addendum to the standard Vector Dynamics instructions. Read and
follow all applicable instructions and guidelines in the Vector instructions and home installation
manual. The Vector system for concrete pads applies to concrete footers, runners and slabs.
Minimum size of concrete per Vector pier is 24” x 24” x 4” or 18” round (min) x 10” deep. The
bottom of footers must be below the frost line or a minimum of 4” below finished grade whichever
is greater. Concrete must be cured sufficiently to prevent spalling at anchors and allow proper
installation. Also refer to ACI-308 standards.
1. Determine location of pier sets where the Vector systems will be located.
2. Place one Vector concrete pad (galv. metal) on the concrete where the pier will be located, centered
under the I-beam of the home. Place the upturned edge towards the center of the home and directed
to the opposite Vector pier. Do the same for the opposite Vector pier.
3. Measure the distance between the two Vector system pads at the base where the Vector pad meets
the concrete. Cut two ground treated 2x4’s or Schedule 40 PVC pipe, or 1 adjustable steel
compression member, part #59043 this length and place between the piers as shown.
4. Place a long u-bolt under the 2x4’s and through the holes of the Vector pad as shown.
5. Place the concrete pier blocks on the Vector pad. Center the blocks under the frame. The upturned
edge end of the Vector pads should be up against the inside of the pier blocks.
6. Build vector piers but do not wedge at this time.
7. Using a concrete drill bit, drill two holes on each side into the concrete using the holes in the Vector
pad as a guide. Drill the 3/8” diameter holes 3 inches deep.
8. Place an outside tension bracket on the Vector pad as shown in Illustration one. Line up the holes in
the bracket, Vector pad and concrete pad.
