Install Stabilizing Systems TABLE 25.ANCHOR SYSTEM MATERIALS SPECIFICATIONS Component Specification Anchors must be tested and listed to resist a minimum ultimate toad of 4,725 lbs and a minimum allowable working load of 3,150 lbs or ultimate and corresponding working load limited by soil conditions and anchor Anchors length.The working load is the maximum load the designer can use.Ground anchors must be provided with protection against weather deterioration and corrosion at least equivalent to that provided by a coating of zinc on steel of not less than 0.30 oz per sq ft of surface coated. Straps must be minimum 1-1/4"x 0.035"zinc-coated(0.30 oz per sq ft)steel strapping conforming to Straps ASTM D3953-97,Type 1,Grade 1,Finish B with a minimum allowable working load capacity of 3,150 lbs and a minimum ultimate load of 4,725 lbs.Slit or cut edges of zinc-coated strapping do not need to be zinc coated. The size and type of stabilizer plate,if required by the ground anchor manufacturer,will be specified in the anchor manufacturers instructions.Stabilizer plates must be provided with protection against weather Stabilizer plates deterioration and corrosion at least equivalent to that provided by a coating of zinc on steel of not less than 0.30 oz per sq ft of surface coated.Alternatively ABS stabilizer plates may be used when listed and certi- fied for such use. STEP 4. INSTALL ANCHORS Before beginning anchor installation, check for obstructions under the home such as piers and frame members that may interfere with the tie down strapping. Check with utility companies to determine the location of underground utilities,such as electrical and phone lines,and water,sewer and gas pipes,that may be buried in potential anc- Grading area hor locations.

In-line anchors can also be installed before the home is set, however precisely aligning the anchor with the home both vertically and horizontally is difficult. Using swivel connectors for the strap to beam connection can provide some horizontal flexibility. To install in-line frame anchors,drive the anchor into the ground at an angle and loca- tion such that a straight line can be drawn from the tip of the anchor through the anchor head and to the connection point on the I-beam(Figure 55).

Properly 'F•• aligning the anchor is critical to performance. Stabilizer Plate Configuration Stabilizer plate configurations(Figure 57)are suitable for homes in all wind zones. Anchors may be installed after the home is set. A stabilizer device,typically an ABS or metal plate, is used to prevent the top of the anchor from slicing through the soil when the load is applied. Stabilizer plates are available in a variety of widths. Choose the widest plate that can be driven into the soil to maximize resistance to movement.The LAHJ may have stabilizer plate requirements. 90
