- The calculated output table below presents 1-4 rows, each with a possible solution listing the type of anchor and the required quantity for one post.
- The costs shown in the output table do not reflect volume discounts.
- The maximum wind information is readily available on the internet by searching for "maximum winds xxxxx" with xxxxx being your zip code.
Use diagonal holes if only 2 anchors are used.
