The calculator below is provided as a tool to select the least-cost anchors to meet the force requirements for a fence.

  1. The critical dimension for the plate hole spacing is D. That is the spacing in the direction perpendicular to the direction of the fence.
  2. Increasing the size D of the plate can save significant costs by reducing the number of anchors required per post
  3. The minimum distance d1 between any two holes is 2"
  4. If possible, install the post so that the longer spacing between bolts is perpendicular to the fence.
  5. Asphalt Anchors assumes no liability for the suitability of the calculations to your actual needs.
  6. 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.
  7. The costs shown in the output table do not reflect volume discounts.
  8. The maximum wind information is readily available on the internet by searching for "maximum winds xxxxx" with xxxxx being your zip code.
  9. The calculations include resistance to a person climbing the fence.
