Earth Anchor Instructions
Do-It-Yourself protection for most outdoor structures or possessions.
- Install ground anchors as close to the building as possible at all four corners.
- Install anchors using a straight rod to turn (screw) anchor into the ground.
- A starter hole, up to 1/3 of the anchor length can be used to start anchor into the ground. Once the anchor eye is level with the ground, backfill the soil and pack area around the anchor eye.
- Anchor eye should be just above soil level.
- Cable can be secured to the building using the following methods.
- Attach one end of the cable to an anchor using the wire rope clips. Cable goes thru the anchor eye and is clamped together using the wire clip. Place the cable over the roof to the opposite anchor, loop cable thru anchor eye. Cut cable to have enough to attach to the anchor. Pull cable tight, attach wire rope clips (2), tighten nuts. Repeat for other side.
- Attach cable to the side wall studs. Additional Eyebolts and Wire Rope Clips and hardware may be required.
NOTE: These instructions are for suggested attachment to small shed not located in high wind areas. For more detailed anchor requirements, see the wind zone charts for your area. You may need additional anchors, cable, wire clamps, or other forms of anchor attachments to the shed to meet local or state requirements.
Calculation Chart Instructions
Example: Wind Zone II chart shows 12' x 18' building:
- Looking in 12' column - Use lowest value in the 12' column for the number of anchors
- *Note: Anchors at the corners shall be counted only once in the quantity required for each side or face of building.
- Maximum 102" building height.
- One Anchor shall be placed at each corner of building.
- Any required anchors between corners shall be spaced equidistant apart from each other.
- Number of anchors required per side shall be determined by finding quantities listed in columns.
