Anchoring Materials

Tie-Down Engineering anchor parts and tools for mobile homes

“J” Hook Concrete Anchors are for use in wet cement and are designed to be used at the time the concrete is poured. These anchors come with a 5/8″ thick rod and a swivel head to allow for the correct alignment.

For use in existing concrete, we offer a Double Tension Head with and expansion shield. These anchors come standard with black paint, but can be ordered with a galvanized dip as is required in some locations.

Optional X Drive Anchors with attached Stabilizer are available and should be used for Soil Class 2 X Drive anchors are not approved for use in all locations. Please check with your local municipal codes before choosing your anchor. Should you need further information, call General Supply today, we will be glad to help

X Drive Anchors are perfect for use in solid rock and should be installed within 1” of the base. The correct alignment is achieved by adjusting the swivel head. These are only approved for class 1 soil conditions

Double Helix Earth Anchors are designed for clay and other hard soils. These double helix anchors are available in 30″ , 48″ and 60″ lengths.

Single Helix Earth Eye Anchors are excellent as a storage building anchor kit. These kits include 4 – 15″ single helix anchors with cable and calms

In soil conditions that may require the use of a stabilizer in addition to your double helix Anchor. General Supply offers a “Deep Set Anchor” with the stabilizer cap attached.

General Supply offers Single 6˜ Helix Eye Anchors that are ¾˜ rods and available in 36˜ and 48˜ lengths. See our catalog for further details

Individual strapping is also available in 37&#39, 60&#39 and 600&#39 sections for people who choose to make

their own tie down straps. Strap buckles and strap hooks are sold individually along with the strap seal and crimp tool to make the job complete.

For Fast Safe and Easy Installation, General Supply offers anchor strapping in 8&#39 and 16&#39 lengths, with your choice of buckle or clamp for I-Beam attachment. The HUD Code requires that all strapping must meet ASTM Specifications. Strapping From Tie-Down Engineering will be properly marked every 12 inches.

REQUIREMENTS
• Install in any type of soil, 4B (175-275 lbs) or better.
• In areas with frost heave, use Xi2 for poured concrete to comply with local requirements for footer depth.
The bottom of the footers must be below the frost line or a minimum of 4” below finished grade,
whichever is greater.
• Maximum vertical projection at sidewall is 9’. Higher walls may be used when the design loads
are adjusted accordingly.
• Poured concrete must be 2,500 PSI minimum at 28 days.
• Square concrete pads minimum is 18” wide by 12” deep. Round concrete pads minimum is 18” wide by
14” deep. Strip footings minimum is 18” wide by 14’ long by 6” deep or 27” wide by 14’ long by 4” deep.
• Main rail spacing must be 75.5” – 99.5”.
• Additional vertical anchor ties that are unique to a home’s design may be required by the home manufacturer.
These locations may include shear walls, marriage line ridge beam support posts, and rim plates. The
longitudinal component of the Xi2 system replaces end frame ties, check manufacturer set up requirements.
• Maximum pier height is 48”.
• Systems must be placed as evenly as possible, no more than 10’ from end of home.
• Additional systems may be needed for roof slopes greater than 20 degrees, 4.37” in 12” pitch, see page 3.
• Two systems designed to work in conjunction with each other.
* Xi2 components exceed HUD code 3280.307g “Anchoring equipment exposed to weathering 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 coating….”

Installation of Concrete Bracket: Dry Set/Wet Set
1. Identify the number of systems to be used on the home using the
chart provided.
2. Identify the location where the lateral systems will be installed.
3. Build pier according to State, Local or Home Manufacturers guidelines.
4a. For dry set: drill two 3/8”x 3” deep holes in the concrete using holes in
galvanized bracket as a guide. Attach bracket to concrete pad using
3/8”x3-1/2” wedge anchors provided. Place nut & washer on anchor, leave
enough room for 1 to 2 threads showing on top of bolt. Using a hammer,
tap the wedge bolts into hole through bracket, leaving nut & washer flush
with bracket. Using a 9/16” socket wrench, tighten wedge/anchor bolt,
securing bracket to the concrete.
4b. For wet set: align bracket and submerge legs completely in concrete.
Bottom of bracket should rest on surface.
5. Attach the end of the smaller tube to the bracket mounted on the pad, using the
grade 5, 1/2” x 2-1/2” bolt/nut provided.
6. Attach the flag end of the larger tube to the opposite I-beam using the
“J” bolt over the top of the I-beam with the nut & washer provided.
(Figure 1 on last page)
7. Install a minimum of four (#12 x 1” Tek screws) self-tapping screws into the holes
provided in the lateral strut so that the two tubes are connected together

When LSD struts are used only as longitudinal stabilization, systems must be as evenly spaced as possible, no
more than 10’ from the end of the home.
Note: Longitudinal stabilization can be combined economically with the Xi2 Lateral System. Combining LSD
struts with the lateral system saves time and material costs. When combining the lateral and longitudinal
systems, use the placement directions for the lateral system.
