Positioning anchor in wet concrete and trowel to grade. The turnbuckle should have forged or welded eyes, not hook ends. The roof protector. If you have exposed over-the-top tie-downs, you must have some sort of roof protectors placed under the strap or cable at the edge of the roof. Roof protectors are also called roof brackets, buffers or thimbles. These prevent the tie-down strap or cable from damaging the roof and will prevent the edge of the roof from cutting through the tie-down.
Wood blocks will work, and are better than nothing, but commercial protectors will do a better job of distributing the pressure of the cable. Commercial protectors will last longer, too. Make sure all your anchoring equipment anchors, turnbuckles, straps, hookups is capable of resisting an allowable working load of at least 3, pounds.
The equipment must also be capable of withstanding a 50 percent overload, 4, pounds. This also applies to the attachment point on the manufactured home. Only use anchoring equipment that is weather and corrosion resistant. Tie-downs can be either cable or strap. If cable is used, it should be galvanized steel or stainless steel.
Tie-down and anchor installation. Installing a tie-down and anchoring system is not too complicated for most do-it-yourselfers. It's wise, however, to seek experienced help to make sure you are using the proper anchor for your soil conditions, enough anchors for your wind conditions, the correct tension on your tie-down, and proper angle for your frame tie-downs. At the very least you should have a building inspector or a trained installer check over your finished work.
STEP 2: Check charts Check the wind zone chart for your location and determine the required number of anchors recommended for your zone.
You should regard this number as the minimum needed for your home. Some types of anchors need to be installed five feet deep. Talk to a building inspector to determine your soil type. If you will be attaching your tie-downs to a concrete foundation, make sure it is at least 4 inches thick. Your soil type will determine the type of anchor. STEP 5: Select hook-up 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, pound capacity. Make sure you have located everything prior to digging. STEP 7: Position over-the-top tie-downs If you are installing an exposed over-the-top tie-down, the strap or cable should be positioned over a roof rafter. Protect the edges of your roof with a roof protector of some type. Make sure the strap or cable does not cover a window or door. Follow them carefully. For a vertical tie-down, the anchor is installed vertically.
This angle should be at least 40 degrees. 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. STEP 9: Adjust tension Alternating from side to side, adjust your tie-downs to the appropriate tension. Don't do one side of your house and then the other. It's important for you to contact the local building inspector for regulations regarding anchoring and blocking installation in your community.
Regulations vary considerably from one community to the next. In some states, tie-downs aren't required. In other states, tie-downs are stringently regulated and inspected. To be tied down safely, find out from your local manufactured home association or building inspector how many tie-downs and anchors you need for your wind and soil conditions.
The cost of installing additional tie-downs and anchors is small compared to the potential cost of wind damage to a manufactured home that was not properly tied down.
