10 Easy Steps on How to Tighten Tension Wire on Chain Link Fence
Step 1. Inspect the Entire Fence:
Begin by walking around your chain link fence to inspect the overall condition, specifically looking for areas where the tension wire appears loose or sagging the most. This initial inspection will help you identify where to focus your tightening efforts. Additionally, check for any damage to the fence fabric, such as holes or tears, as these may need to be repaired before tightening the tension wire.
Step 2. Remove Old Tension Bands:
Start by carefully removing any old or damaged tension bands currently attached to your fence. These bands typically secure the tension wire to the posts along your chain link fence. If they’re too tight or rusted to be reused, you can use wire cutters or pliers to cut them.
Ensure you do this carefully to avoid damaging the fence posts or the tension wire. Removing old tension bands is necessary to provide a clean start for re-tightening the wire with new hardware, ensuring maximum efficiency and support.
Step 3. Attach New Tension Bands:
Once all old tension bands have been removed, it’s time to install new ones. Position a new tension band around each post where the old ones were removed. Ensure that the bands are placed at the same height on each post for uniform tension wire support.
The flat side of each band should face outward, with the open end pointing downwards. This positioning facilitates easier attachment and adjustment of the tension wire throughout the fence’s length. Tighten each tension band loosely at this stage, as you’ll need some flexibility when you thread and tension the wire.

Step 4. Thread the Tension Wire:
Begin at one end of your fence, attaching the end of the tension wire to the first post using a tension band. Make sure the wire is looped through the tension band and secured in place. Now, unroll the tension wire alongside the fence, ensuring it lies at the bottom of the fence fabric, and thread it through each tension band attached to the posts.
It’s important to keep the tension wire on the inside of the fence to prevent it from being tampered with from the outside. When you reach the end of the fence, cut the wire, leaving enough length to secure it to the final post.
Step 5. Secure the Wire at the End Post:
At the final post, secure the end of the tension wire using a wire clamp. Loop the wire through the tension band on the last post and then back through the wire clamp. Pull the wire tight to ensure there is minimal slack. Once the wire is taut, tighten the clamp to secure the wire in place.
This step is critical for maintaining the tension throughout the entire length of the fence, ensuring that the wire supports the fence fabric effectively and prevents sagging.
Step 6. Adjust the Turnbuckle for Tension:
Introduce a turnbuckle at a convenient point along the fence line, ideally in the middle, to manage the tension of the wire efficiently. Attach one end of the turnbuckle to the tension wire using another wire clamp. Then, connect the other end of the turnbuckle to a fixed point on the fence or another section of the tension wire.
By turning the turnbuckle, you can adjust the tightness of the tension wire. Ensure the tension is even throughout the length of the fence to prevent any part from being too tight or loose. This step is crucial for achieving optimal tension, contributing to the longevity and effectiveness of the fence.
Step 7. Check and Adjust Tension Wire Evenly Across the Fence:
Once the turnbuckle is in place and you’ve adjusted the tension wire to be fairly tight, walk along the fence line to check the tension wire’s tightness at various points. It’s important to ensure that the wire is evenly tight across the entire length of the fence to maintain uniformity and strength. If you notice any sections where the wire is too tight or loose, adjust the tension using the turnbuckle.

This step may require several adjustments to achieve the perfect balance of tension across the whole fence, ensuring it supports the fence fabric evenly and effectively.
Step 8. Reattach Fence Fabric:
After ensuring the tension wire is properly tightened and uniformly across the entire length of the fence, the next step involves reattaching or adjusting the chain link fence fabric as needed. Start at one end of the fence, securely fastening the fence fabric to the first post using suitable ties or fasteners.
Gradually stretch the fabric along the length of the fence, attaching it at several points to maintain tension. Ensure that the bottom of the fabric is properly aligned with the tension wire, providing additional support and stability to the fence structure. This process might require multiple adjustments to ensure that the fabric is neither too loose nor overly stretched, which could compromise the integrity and appearance of the fence.
Step 9. Final Inspection and Maintenance Tips:
After all tension wires are tightened and the fence fabric is secured, conduct a final inspection of your chain link fence. Walk around the fence to ensure everything is in proper order, with no loose tension wires or sagging sections of fence fabric.
Pay special attention to the tension bands, turnbuckles, and wire clamps to ensure they are tightened and secure.
Regular maintenance is crucial for extending the life of your fence. Check the tension wire and fence fabric periodically, especially after severe weather conditions, to ensure they remain tight and intact. Lubricate the turnbuckles and wire clamps as needed to prevent rust and ensure smooth operations for future adjustments.

Step 10. Enjoy Your Refreshed Fence:
Finally, take a moment to step back and appreciate your hard work. Your chain link fence is now fully tensioned, with the fabric securely attached and all hardware in place. This refreshed fence looks better and provides improved security and durability. Remember, the lifespan of your fence can be significantly extended through regular checks and maintenance.
