How to Tighten Barb Wire Fence


Barbwire fences are used for many purposes on farms and in urban areas. They can keep animals in or out of a particular place and provide an additional layer of security around the property. Barbwire is also often seen surrounding construction sites to discourage potential thieves from trying to steal building materials. Barbwire is very dangerous, though.

How to Tighten Barb Wire Fence

Being around barbwire fences for any length of time is not recommended. Barbwire fences are made by attaching wires to wooden posts and then twisting barbs onto the wires between two twists of wire. This creates what appears to be a sort of thick, spiky rope that is hard to climb or cut through without help. In this article, I will discuss how to tighten barb wire fence. So let us get started.

A Detailed Stepwise Guide on How to Tighten Barb Wire Fence

It might seem like barb wire would be difficult to work with, but it’s pretty simple if you know what you’re doing. Here are some steps for tightening barb wire fencing:

Step 1 – Set the Tension

Before you even begin working with the fence, make sure there is tension on all of your lines. To do this, run along your borders and pull gently to test if they are taut. If you see any loose strands or sagging wires, secure them by clipping off any excess wire with wire cutters and retying the ends of each wire, so it is tight against the wooden post to which it is attached. Ensure that none of your wires are too close either; allow them to move just a little bit, so they don’t break overdue to stress.

Step 2 – Cut the Wire

Now, get out your wire cutters and cut off any spots with too much excess wire. When you do this, make sure that you only remove the excess and not a large section of the line; if you try to take too much off at once, you run the risk of getting cut by the sharp ends left behind.

Make sure that you leave one strand on each post so that there is still something holding each strand in place. If all of your strands are sagging or loose, go ahead and tighten them up before cutting just enough to give yourself some extra space to work with.

Step 3 – Secure New Sections

Once your lines have been tightened up and any excess removed from around the posts, you can begin adding new strands to your fence. First, add in a single strand of wire by tying it to one of the posts. Then, take another piece and attach it to be about two inches between them; when you do this, make sure that both pieces run straight down from the top wire so that they are parallel with each other.

Step 4 – Replace Lost Sections

If any sections have broken or fallen out over the years, now would be a good time to replace them. Run a single strand of barbed wire between two old ones and clip off all excess lengths so that only the top strand extends past where the post begins. Make sure not to cut yourself on any sharp ends left behind!

Step 5 – Tying Off

After you have your three strands in place, you need to tie them off to not move to around too much. To do this, make a simple knot for each strand by tying them together at their ends. Make sure it is secure; if not, the strength of the fence could be compromised!

Precautions While Tightening Barb Wire Fence

1. Before you start to tighten, make sure that a cutter cuts the barb wire and there are no edges of barbs facing upwards. Otherwise, it can cause injury.

2. If your farm animals or other animals have been trapped in the fence, try to release them before starting to tighten as this will make them stressed, which may lead to their death due to suffocation from the drawing of the fence.

3. The first step should be tying-in to avoid any damage during tensioning of the line wires if barbed wire rollers are not available.

4. Ensure that all posts are strong enough not to get pulled out during the tensioning process, and fix all loose fittings with nails or screws.

5. Don’t try to tighten the line wire while some posts are still moving as this will cause a big problem and may lead to injuries or deaths of farm animals or other livestock.

6. To avoid any accidents during the tensioning process, use only manual tools for tightening barb wire fences such as spanners, pliers, timber wedges, etc. never use machines because if it digs into the ground, then there is a strong possibility that the device itself get damaged and become unusable. Thus it would be better to use your hands so you can quickly release them from the soil in case of emergencies.

7. While you are tightening barbs by turning them with spanners or wrenches, do not go too close to the post; otherwise, it will become difficult to release the line wire from the tightened, and this will cause a problem.

8. While tightening, stop whenever you feel that posts are getting pulled out of their place or are under stress because if they come out, then your work would be nothing but a waste of time and materials which would have been used for tightening barbs.
