Stretching a Field Fence

There are a wide variety of uses for a field fence. Some are bright orange plastic and are used by contractors to delineate lots and for erosion control. Others, usually chain link or barbed wire, will be used to mark out property lines or create separate enclosures for livestock. Over time, these will lose their tension and begin to sag. Stretching them to restore their tension and remove sags is quite easy with the right tools and information. The paragraphs below will provide you with a list of the required tools and some easy to follow steps to follow to stretch your field fence.

Tools Required for This Project

  • A heavy duty hammer
  • Leather work gloves
  • Eye protection
  • Adjustable wrench
  • Lineman’s pliers

Step 1: Remove Intermediate Straps

The first thing you need to do in order to stretch your field fence is to walk the fence line and, using the lineman’s pliers, remove all of the intermediate straps holding the fence to the posts. Lay these on the ground at the foot of the posts for future use.

Step 2: Loosen Stiffener Clamp at One End

Choose andend of the field fence to start on after all of the intermediate straps have been removed. At the end, loosen the nut and bolt securing the diagonal stiffener pole to the upright fence post.

Step 3: Hammer Diagonal Stiffener Down

With the stiffener clamp loosened, use the hammer to drive the upper end of the diagonal stiffener towards the ground. Since this stiffener is at an angle, this will push the fence post out at the top, stretching the fence. Try to take up at least half of the sag in the fence on this one side. If this isn’t possible, you will need to remove the clamps holding the fence to the post, then remove the clamp on the diagonal stiffener and re-position the post so that the proper tension will be applied to the fence. If this is the case, you will need a shovel and a fence post driver. If enough slack and sag has been pulled out of the fence, tighten the diagonal stiffener clamp to the vertical fence post.

Step 4: Stretch Other End

Go to the other end of the fence and loosen the stiffener clamp.

Step 5: Hammer Diagonal Stiffener Down

With the stiffener clamp loosened, use the hammer to drive the top of the diagonal stiffener down against the fence post. Again, if the proper tension to remove the sag can’t be achieved with this method, you will need to reposition the fence post a few inches to provide the proper tension.

Step 6: Reattach Clamps

Walk the fence line and reattach the fence clamps to clamp the field fence itself to each of the individual posts. You should use at least two clamps, at the top and bottom. It’s also recommended to use one clamp in the middle of each post.

After following the provided instructions, you will have stretched your field fence, removing the sag from it and extending its useful life.
