Full details
The KATSU Tools 20-Pack Electric Fence Ratchet Tensioner is designed for farmers, fencing contractors, and agricultural professionals who need a durable, reliable method for maintaining wire tension in perimeter fencing. Its primary benefit is the 800lb maximum breaking strength, which ensures long-term stability for high-tensile wire setups, though users must remember that a specialized spanner is required to operate the ratchet mechanism.

FAQs
Can I use these on barbed wire?
These are designed for standard steel wire, cable, and rope; usage on barbed wire is not recommended as the barbs may interfere with the spool mechanism.
Does the pack include the spanner?
No, the special spanner required for operation must be sourced separately.
Are these rust-proof?
They are made from high-grade casting aluminium alloy, which offers excellent resistance to rust and corrosion in outdoor environments.
What is the maximum wire diameter allowed?
The tensioners are compatible with any wire, rope, or cable with a diameter of 4.5mm or less.
Can I use these to splice two wires together?
Yes, the design acts as an inline joiner, making it perfect for splicing broken fence lines.
Troubleshooting
The tensioner will not hold the wire tight.
Check the anti-reverse gear for debris or damage; ensure the spring clip is fully engaged in the gear teeth.
Spanner does not fit the ratchet center.
Verify that you are using the correct manufacturer-specified spanner, as standard wrenches will not fit the gear drive.
Wire slips out of the tensioner.
Ensure the wire diameter is under 4.5mm and that it has been threaded correctly through the spool slot.
Pros and Cons
Pros
- Durable cast aluminium alloy construction
- Anti-reverse gear ensures reliable, long-lasting tension
- Dual-purpose functionality for tightening and splicing
- Strong 800lb breaking capacity suitable for livestock containment
Cons
- Requires a separate specialized spanner for operation
- Limited to wire/rope diameters under 4.5mm
- Not intended for high-tension synthetic mesh fencing
Setup, Compatibility & Care
To install, thread the wire ends through the ratchet core. Use the specialized spanner to rotate the spool, which winds the wire onto the internal drum until the desired tension is achieved. Once the tension is set, the spring clip locks the gear, preventing backward rotation.
- Compatibility: Only use with wire, cable, or rope measuring 4.5mm or less in diameter.
- Maintenance: Periodically check that the anti-reverse gear is free of debris or heavy corrosion. Applying a light lubricant to the gear mechanism once a year can prevent seizing in harsh outdoor climates. Always ensure the tensioner is correctly aligned with the line of pull to avoid lateral stress on the spool.
