Splicing poly rope electric fences is a necessary skill for anyone maintaining an electric fence. It is a simple process that requires some basic tools and materials. Poly rope electric fences need to be spliced for two main reasons: to extend the length of the fence and to repair breaks in the wire. A strong and permanent splice can be achieved using crimping sleeves, while a temporary solution can be created by simply tying the ends of the polywire together with multiple knots. This guide will teach you how to splice poly rope electric fences safely and effectively, ensuring your fence is properly protected and energized.
| Characteristics | Values |
|---|---|
| Reasons for splicing | Extending the fence's length, connecting polywire from one spool to the next, repairing breaks in the fence |
| Tools required | Crimping sleeves, voltage tester, gloves, crimper tool |
| Steps | Turn off power to the fence, check power is off with voltage tester, slide crimping sleeves over one end of polywire, slide second poly wire through sleeve slots, squeeze sleeves tight with crimper tool, test strength of connection, turn power back on, check voltage levels on each side of splice |
| Alternative method | Tying ends of polywire together with multiple knots (temporary solution only) |
| Considerations | Ensure all individual wires are in contact to pass on electrical charge, heavier-duty polywire has stronger mesh and more wires |

When to splice: extending a fence or repairing breaks
Splicing is required on electric fencing for two main reasons: extending a fence and repairing breaks.
Extending a fence
If you need to extend your fence beyond the length of a single spool of electric poly wire, splicing is necessary to link the polywire from one spool to the next. This will allow you to properly protect and seal off an area, such as a paddock.
Repairing breaks
Polywire can snap due to various reasons, including falling objects, vehicle intrusion, or stress applied by fenced-in livestock or wild animals. When this happens, a section of the fence becomes de-energized, and splicing is the best way to quickly re-establish the electric connection and repair the break.
It is important to note that splicing should be done with crimping sleeves or by tying the ends of the polywire together with multiple knots to ensure a secure and safe connection.

Prepare: turn off power, test voltage, and wear gloves
Before splicing poly rope for an electric fence, it is important to take the necessary precautions to ensure your safety and the effectiveness of the splice. Here are the steps to prepare:
Turn off the power to the fence. This is a crucial first step to avoid any accidents or electrical shocks while working on the fence. It is always better to be cautious when dealing with electricity.
Test the voltage to make sure the power is indeed off. Use a voltage tester to verify that there is no more electricity flowing through the fence. This step is important for your safety and to ensure that you are working with a completely de-energized fence.
Wear gloves for protection. Electric fence poly rope is made of several thin wires woven into a plastic mesh. To protect your hands from the sharp wires and to provide insulation, it is important to wear gloves. Gloves will also provide a better grip when working with the poly rope.
It is important to note that creating a splice is a common way to extend the length of an electric fence or to repair a broken section. A strong and permanent splice can be achieved using crimping sleeves, which are metal fittings designed to re-establish an electric connection between two pieces of poly rope.
By following these preparation steps, you can help ensure your safety and create a more secure and effective splice for your electric fence.

Using crimping sleeves: slide and squeeze for a strong connection
Using crimping sleeves is a great way to splice poly rope electric fences. This method creates a strong, permanent connection and is perfect for extending your fence or fixing a break in the line.
To begin, ensure your fence's power is off and use a voltage tester to double-check. You should also put on a pair of gloves for safety. Next, take three crimping sleeves and slide them over one end of the poly rope. Then, take the other poly rope and slide it through the open slots on the sleeves. You should now have the two poly ropes connected by the three crimping sleeves.
Using your crimping tool, squeeze each sleeve tightly to create a strong connection. The clamping action of the crimping sleeves will hold the poly ropes in place and establish the necessary electrical connection. To test the durability of your splice, pull on each end of the poly ropes to see if they slide out of the sleeves. If they do, simply use the crimping tool again to squeeze the sleeves tighter.
Finally, turn on the power to the fence and use the voltage tester to check the voltage levels on each side of the splice. If one side shows a significantly lower voltage, you may not have a good connection and might need to redo the splice.

Test the strength: pull ends to ensure poly rope doesn't slide out
Once you've spliced your poly rope electric fence, it's important to test the strength of your splice. This is a crucial step to ensure the poly rope doesn't slide out under tension and that your fence is secure.
Start by donning a pair of gloves for safety. Then, firmly grasp each end of the spliced poly rope and pull. It's important to pull with a decent amount of force to simulate the tension the fence might experience in use. If the poly rope slides out of the crimping sleeves, it indicates that your splice is not secure enough and needs to be redone. In this case, release the tension and adjust your sleeves. You can then try crimping again with your tool, ensuring an even tighter connection.
The strength test is a simple but effective way to ensure the integrity of your electric fence. By pulling on each end, you're simulating the stress the fence might endure, whether from livestock, wild animals, or other external forces. A proper splice will ensure that your fence remains intact and functional, keeping your paddock securely sealed off.
It's worth noting that a strong and permanent splice is achieved through the use of crimping sleeves. These metal fittings are designed to securely hold the poly rope in place and maintain an electric connection between the two sections of the rope. By testing the strength and adjusting as needed, you can be confident that your fence is both effective and safe.

Tying knots: a temporary fix when crimping tools aren't available
Tying knots is a temporary fix when crimping tools aren't available. It is a quick solution to splice poly rope electric fences, but it is important to remember that it is not a long-term solution.
To start, grab the two wires or broken pieces of poly rope that you want to connect. Ensure that the fence's power is turned off, and use a voltage tester to make sure. Then, tie the two ends together with multiple knots. An offset knot is a good option, where you gather the two ends of the rope side by side to form a 6-inch tail, then loop and pull it tight. You can also do a square knot if you don't want to untie it or a sheet bend if you might want to undo it later.
After tying the initial knot, twist the two-knot sections upon the poly wire to achieve a neat and sturdy connection. Make sure that all the individual wires are in contact to pass on the electrical charge down the fence. The more knots, the better the electrical connection. However, be aware that if your livestock or cattle test the knots, they may slip or break.
While tying knots is a simple and quick solution when crimping tools are unavailable, it is not a substitute for a proper splice using crimping sleeves and a crimping tool. This method will ensure a strong and permanent connection.

Frequently asked questions
Splicing is required on electric fencing for two main reasons: to extend the length of a fence, and to quickly re-establish a broken section of fencing.
You will need a voltage tester, gloves, crimping sleeves, and a crimper tool.
First, turn off the power to the fence and use a voltage tester to ensure the power is off. Then, wearing gloves, slide three crimping sleeves over one end of the poly rope. Hold the sleeves in place and slide the second poly rope through the open slots on the sleeves. Use a crimper tool to squeeze each sleeve tight, creating a strong connection.
Test the strength of the splice by pulling on each end of the rope to see if it slides out. If it does slip, simply use the crimping tool again.
If you don't have crimping sleeves or a crimping tool, a temporary solution is to tie the two ends of the poly rope together with multiple knots. However, this method should be avoided if the fence is meant to contain livestock, as the knots may slip or break.
