De-Fence Planning

1. Planning & Preparation
  • Survey site carefully
  • Mark out corners
  • Mark out changes of direction in the fence line

De-Fence Tip

Select your starting point ensuring that you are working down the slope. This makes stepping and post setting easier.

7. Double Check Levels and Continue

De-Fence Checking Levels Tip

De-Fence Tip

IT IS VERY IMPORTANT TO CHECK AND RECHECK.
Always return to the previous 3 posts and panels you have placed and check the levels. The panels can sometimes hang and pull the posts off the vertical. This is very hard to rectify at a later stage and also creates assembly problems at the corners.

8. Stepping the Panels
  • Follow the slope of the ground and step your panels
  • Slacken off the bolts and slide the panel down
  • Ensure you get an even step over the entire distance
