INSTALLATION INFORMATION
Anchor Installation
1. Position anchor at a slight back angle (10˚) so that when fully installed, the anchor head will be inside any skirting or side wall.
2. Install anchor to +/- 2/3 depth, then install stabilizer vertically, within 3”-4” of anchor shaft, parallel to wall of home.
3. Fully drive anchor, attach strap (see proper strap tensioning), and pretension strap to pull anchor rod against the stabilizer plate.
Manual Anchor Installation
1. Dig holes to a depth of 2/3 of the anchor length. Install anchor with rod or length of pipe for leverage.
2. Replace earth in hole after anchor/plate is installed at full depth. Pack dirt with a tamping rod every 6 inches of fill.
3. Testing may be required in loose soil conditions to check that anchor has proper holding power.

Important: Anchor must be installed to full depth. Anchor head must be at ground level or at the top of the stabilizer plate which is fully installed to ground level.

Electric Drive Machine Installation
Operating Instructions:
1. Attach adapter head to shaft of the EDM motor, tighten set screw.
2. Place extension handle in the end of the EDM if needed.
3. Place anchor head into adapter, line up anchor shaft with EDM shaft, for easier installation.
4. Flip forward/reverse switch to forward.
5. Place anchor tip in location where anchor is to be buried. Hold on/off switch to install.
EDM Adapter Head.
Electric Drive Machine Cautions and Warnings:
• Before installation of any ground anchor, determine that the ground anchors to be installed will not be near any underground electrical cables, phone lines, water lines, sewer pipes, or gas lines. Failure to do so may result in serious injury or death
• The EDM is designed for operation by two people.
• Do not allow the EDM to be wedged against the home or other solid objects, when operating the EDM.
• Electrical cord must be a minimum of 14-2 wire size w/ground up to 25 ft. of cord. Longer cords must be 12-2 wire size w/ground or lower.
• Never operate the EDM in wet or rainy conditions.
• Frayed or patched electrical cords should never be used with the EDM.
• Care should be taken to keep electrical cords away from anchors.
• Never operate drive machine without the GFI power cord. Damage to motor and injury to operator can r esult from by passing the GFI.
• The GFI will shut off power when a ground fault is detected. The GFI will also shut off power when it detects low voltage improper amps required to drive the motor. Many times the problem will be the use of an extension cord that is too long or is too light in gage.

Anchor Stabilizer
In order to prevent lateral movement of manufactured homes subjected to high wind loads and to comply with HUD’s Wind Zone I, II, & III requirements, all lateral frame ties must be attached to a properly stabilized ground anchor. (Two approved methods illustrated below.)

ABS Stabilizer Plate
10” x 24” Part # 59293
Quik-Set Stabilizer Plate
Black Paint: Part #59291 Galvanized: #59291G
Stabilizer Plate Installation
1. Refer to any and all local, state and federal regulations.
2. Use the Soil Test Probe at the anchor location in order to match soil class with the anchor/stabilizer.. (See Page 11)
3. Partially install anchor to allow 14” to 16” remaining above ground level.
4. Utilizing oversized hammer, vertically install stabilizer plate, nesting anchor rod in between formed channels on outside of stabilizer plate (between anchor and frame).
5. Fully install anchor so that head is at the surface of the soil (1” tolerance, if necessary) and pretension anchor until touching stabilizer plate.
ABS Stabilizer Plate
Part # 59293
1. Determine correct anchor to be used with the home installation and use the manufacturer instruction for installation, following all safety precautions.
2. Using an electric drive machine, install anchor to a depth of approximately 28 inches at a slight back angle.
3. Dig out an 8” wide area so that the ABS stabilizer will be placed on undisturbed soil at a 10 to 15 degree angle toward the home. The bottom center of the plate should be touching the anchor rod.
4. Complete the installation of the ground anchor until the bottom of the anchor head is flush with the ground.
5. Attach proper strap and tension strap until anchor head is flush against the ABS plate and strap is tight. At this point, soil should be tamped into the vacant area behind the anchor rod, tamping approximately 6” and repeating until the vacant area is flush with the surface of the surrounding ground.

Direction
1. Install ground anchor inside skirting line at a slight back angle of 10˚ - 15˚.
2. While anchor head is still 5” to 6” above ground level: install Quik Set stabilization plate around anchor shaft, referring to the direction imprinted on the top of the plate.
3. Install ground anchor until Quik-Set plate is fully set. Hammering may be required at the corners to insure plate being fully driven.
4. Install strap(s) to anchor head and pretension according to approved methods. Maximum anchor load in conjunction with the “Quik-Set” device is 4725 lbs. (ultimate).
Deep Set Anchor/Stabilizer Instructions
1. Confirm soil classification using standard torque probe at 36” below ground surface, make certain readings meet or exceed 350 in lbs. (Class 2 and 3 soils) at the depths of 12” & 36”.
2. Clear loose vegetation where anchor will be installed. Install anchor vertically to its’ full depth. Stabilizer plate at the top of anchor must be fully embedded into soil.
3. Pull strap past anchor head and cut strap so that there is 12” to 15” of strap to wrap onto anchor bolt insuring 4 to 5 wraps minimum.
4. Insert strap into anchor bolt flush with opposite side of bolt. Tighten bolt/strap until tight. Secure anchor bolt with nut.
45˚ maximum (if angle exceeds 45˚ attach additional strap tie to opposite frame)
Certified Galvanized Strapping*
DOUBLE THICK G-60
GALVANIZED PROTECTION
The steel strapping by Tie Down Engineering for the manufactured housing industry has been tested to, and conforms to, the HUD Code as referenced in Part 3280 of the Manufactured Home Construction and Safety Standards and Part 3285 of the installation standards; Final Rule.
3280.306(f), 3285.402(b2) Anchoring Equipment – Load Resistance. Anchoring equipment shall be capable of resisting an
allowable working load equal to or exceeding 3,150 pounds and shall be capable of withstanding a 50 percent overload (4,725 pounds total) without failure of either the anchoring equipment or the attachment point on the manufactured home.
3280.306(g), 3285.402(b2) Anchoring Equipment – Weatherization. Anchoring equipment exposed to weather-
ing shall have a resistance to weather deterioration at least equivalent to that provided by a coating of zinc on steel of not less than 0.30 ounces per square foot of surface coated, and in accordance with the following: (1) Slit or cut edges of zinc-coated steel strapping do not need to be zinc coated. (2) Type 1, Finish B, Grade 1 steel strapping, 1-1/4 inches wide and 0.035 inches in thickness, certified by a registered professional engineer or architect as conforming with ASTM Standard Specification D3953-91, Standard Specification for Strapping, Flat Steel, and Seals.
The above specification of a minimum coating of 0.30 ounces per square foot equates to a designation of “G30.” Tie Down strapping exceeds this minimum requirement with a coating of
0.60 (G60) or 1.20 (G120) ounces as per above. Similarly, Tie Down strapping exceeds, in testing, the minimum load require­ments of 3,150 pounds design (working) load and 4,725 pounds (ultimate) overload.
* Available with G60 or G20 galvanized coatings.
