Cut off the anchor strap leaving 8 inches beyond the anchor. Put the split bolt loosely into one of the square slots and turn the nut onto the bolt, one turn only for now. Old straps used to be wrapped around the steel I beam this is not longer allowed. The bolt holes in the anchor head should be parallel to the side of the home.
Unlike a big box store or a conventional hardware store, mobile homes are all that those who work in a specialty service and supply business do. They can help with the analysis of weather and wind maps, soil conditions and best assist their customers with the right products and know-how for a successful outcome. Manufactured homes must have anchors and tie-downs to keep them in place during high winds. Compared to site-built homes, manufactured homes are relatively lightweight. They have flat sides and ends, and they are built on frames rather than foundations. Almost all manufactured homes are elevated, situated on top of some sort of pier or foundation system.

If you will be attaching your tie-downs to a concrete foundation, make sure it is at least 4 inches thick. Installing a tie-down and anchoring system is not too complicated for most do-it-yourselfers. At the very least you should have a building inspector or a trained installer check over your finished work. It is important to note that the requirements for your local area can vary quite a bit from what is shown above.
The anchor can be installed vertically if you also install a stabilization device to keep the anchor from moving sideways. A metal stabilization device can be attached to the top of the anchor and buried in the ground. Another option is to pour a concrete collar around the top of the anchor. The collar should be at least 10 inches in diameter and 18 inches deep. Whatever type of anchors you select, carefully follow the installation instructions. Auger anchors (screw-in anchors) can be installed manually by inserting a metal bar through the top of the anchor for added leverage or with a machine designed for this purpose.
How To Mark The Anchor Location On The Ground.
Position anchor at a slight back angle (10˚) so that when fully installed, the anchor head will be inside any skirting or side wall. We will then attach the end of the strap to a turnbuckle as seen in the picture above. Turnbuckles are used to tightened and increase the tension on the strap and remove any slack to secure your mobile home in place. Decorative blocks or decorative wood lattice offers you less wind resistance that could lift your home off the ground during high wind events like a hurricane. Drive anchors are bored into hardened concrete, brick, or block.
Write down the steps for installation with a timeline for finishing important tasks. This ensures that the work is done in a timely and correct fashion. Next, you will need to turn the anchor in a clockwise direction applying some constant pressure with your body weight in a downward direction as you turn.

In short, there isn’t really much leeway in selecting your foundation, but you should make your GC aware of any lender or park requirements. There are several companies that offer more general home warranties for your mobile home that you can read about here. To request a prospectus of investment opportunities at Home Nation. Turn the split bolt until the strap is wrapped around the bolt 4-5 times and all of the slack has been removed. Insert the strap through the slit in the split bolt with the end of the strap flush with the bolt.
This is preferred as one crew performing both functions can result in a seamless flow of services on site. This isn’t a problem as long as everyone communicates, everyone knows their distinct responsibilities, and everyone knows where the buck stops. When things go wrong, it’s usually because the work is not properly coordinated and overseen. Check to make sure that the anchors aren’t being pulled up from the soil. Many anchors are driven into the ground so that only a few inches are visible above ground.
They can be used in all wind zone conditions, except ”Exposure D” within 1500 ft. of the coastline. Anchor types include but are not limited to auger, rock, and drive anchors. Anchors will usually be installed by inserting a metal bar through the top of the anchor for added leverage or with a machine designed for this purpose. The tie-down must be connected to the anchor with a system that allows for adjusting the tension. It must also be weather resistant and strong enough to support as much weight as the anchor and tie-down. Virtually all newer-model manufactured homes have increased structural strength and are secured with anchoring straps that are attached to steel frame rails called frame anchors.
If there’s one takeaway, it’s that everything hinges on hiring the right crew. Before you sign anything, meet with the installers and conduct a final walk through of the home. This is an exciting moment – if everything goes well, you’re about an hour away from getting the keys.
To resist wind forces, you need two different types of tie-downs. In older homes, a vertical or over-the-top tie-down is needed to compensate for the uplift force. A diagonal or frame tie-down is needed to compensate for both lateral and uplift forces. Singlewide manufactured homes need both types of tie-downs. Underhome Armor will determine which type of mobile home tie down and straps are required in your area. For a frame/diagonal tie-down, the anchor can be installed to the same angle as the tie-down.
Mark the location of your electric, cable, gas, water, sewer and phone lines on the ground before you install anchors. Depending on your tie-down system, over-the-top or frame, select the appropriate hook-up and tensioning device. Make sure the entire system is certified to a 4,725 pound capacity.
You won’t be permitted to move in until the home passes inspection and the inspector issues a certificate of occupancy. This also triggers a notice to the utility company to activate power. Your set-up crew will arrange for state inspection since it is ultimately their responsibility to ensure the installation has been completed in compliance with state regulation. Steel Support Piers are designed for use as a replacement for dry stacked blocks, piers available up to a maximum of 30 inches. Steel Support Piers are designed and tested to vertical loads for a support rating of 6,000 lbs.
You’ll need a crane to position the home if you’re using basement foundations. Remove packing materials that protected the home during shipping. Inspect the home and all provided materials, appliances and equipment immediately upon delivery.
The number of anchors you need will vary based on your grade and other factors. Many anchors are able to accommodate both a vertical and diagonal tie down on the same anchor. Older anchors installed prior to 1997 were more than likely made of non galvanized steel which deteriorates rapidly. This is especially true in a wet area where flooding occurs and water stays under the home for any length of time. Anchors are connected to the home with galvanized steel swivel straps and a beam hook. Fully drive anchor, attach strap , and pretension strap to pull anchor rod against the stabilizer plate.
Mark the location of the anchor on the ground directly below the attachment point on the home or shed.

If your home has special site considerations, a registered professional engineer or architect can devise an alternate anchoring system. Ensure that all lines have been marked off before you begin the installation. This way, you can know where these lines are, and prevent any disaster from occurring.
