For all Wind Zones,connect an anchor strap from the anchor head to the beam closest to the anchor. See Figure 67. In-line anchor configuration and Figure 68. Stabilizer plate configuration.For Wind Zones II and III connect a vertical strap from the sidewall factory installed tie of the home to the anchor head using a double-headed anchor;connect the other strap to the beam closest to the anchor. Refer to Table 22 for maximum heights from ground. • Far beam method.For Wind Zones II and III connect one anchor strap from the anchor head (using a double-headed anchor)to the home's near beam or far beam and one to the sidewall of the home. Refer to Table 23 andTable 24 for maximum heights from ground. STEP 3. SELECT ANCHORS Use the torque probe results from Prepare the Site,STEP 5.DETERMINE SOIL- BEARING CAPACITY AND FROST LINE(p. 14)and the anchor manufacturer instruc- tions; select the type and length of anchor to use.The installed ground anchor size (length)must be listed (i.e.approved)for the soil class. Make sure the anchor is of sufficient length such that the top of the helix is below the frost line. Select a shaft diameter sufficient to resist excessive torsion,"ring-off" (when D the helix or anchor head separates from shaft)or shaft splitting. Consult the anchor D supplier for guidance. ..a Review all of STEP 3.
