Tie Down Vector Dynamics Foundation System for Wind Zones lll - Manual (Page 11)

9. Put a washer and nut on one of the 3/8” x 3-3/4” wedge anchors. The nut should be screwed on
enough to have 1 or 2 threads showing on the top of the bolt. Place the wedge end of the bolt into
one of the holes, going through the outside tension bracket, metal Vector pad and into the concrete.
10. Using a hammer, tap the wedge bolt into the hole. Maximum height for expansion bolt above
concrete is 2”.
11. Repeat for the other hole in the outside tension bracket and the two holes on the other Vector
system pier set.
12. Place an inside tie bracket over the u-bolt so that the lip of the bracket is between the Vector plate
and concrete blocks. Place washers and nuts on each U-bolt. Do not tighten yet (see illustration two).
If adding longitudinal stabilization, drill the two holes on the side using the pad as a guide.
Insert wedge anchors using the same method as 8-11.
13. Install strap protectors over I-beam and bend into place. Attach a hook or swivel strap to the inside
tie bracket, with sufficient length to go over strap protector on opposite I-beam and down the
outside of the pier to tension bracket, plus 12 inches for wrapping bolt. (If using hook, place
hook underneath the inside tie bracket flat against the compression board) repeat for opposite side.
14. Tighten inside u-bolts at this time.
15. Use the outside tension brackets to remove any space between the outside tension brackets,
concrete blocks and the inside edge of the Vector pad, by tapping the brackets with a hammer.
Wedge the pier set at this time.
16. Using a 9/16” socket wrench, tighten all of the wedge/anchor bolts, securing the outside tension
bracket and Vector pad to the concrete.
17. Using a slotted bolt in the outside tension brackets, insert strap through slotted bolt with end of strap
aligned with outside edge of bolt. Turn slotted bolt until straps are tight using at least 4 to 5 turns on
the slotted bolts.
