A single stainless steel electric fence tensioner spring, sold on its own for a repair or to finish one strand. It is a coil tension spring with a loop at each end and a stiff limiter wire fitted to the spring. The spring keeps the fence wire tight as it expands in the heat and shrinks in the cold, and the limiter stops the spring overstretching when the wire is pulled hard. If you are fitting out a whole fence, the same spring comes as a pack of 50.
What the limiter does
A coil spring that is stretched past its limit does not pull back to its original length, and from then on it holds the wire loosely. The limiter is a stiff hairpin of wire fitted to the spring: once the spring reaches the length the limiter allows, the limiter takes the pull instead of the coils. The spring keeps its tension for the life of the fence wire instead of going slack after the first knock.
How it fits on the fence
Hook one loop onto the fence wire and the other onto the spring hook or end insulator at the bracket, pull the strand tight and make the wire off with a line clamp or ferrule. There is no ratchet on this spring, so you set the tension when you fit it. If you want a spring you can tighten again later with a ratchet, look at the Nemtek Hybrid Compression Spring 1.
Electric fence tensioner spring with a limiter, or a Nemtek spring?
The maker of this spring does not publish a pull rating or a wire size, so we do not quote one. Nemtek rates its springs: the Compression Spring 1 is the standard 5kg spring without a ratchet, and the Hybrid Compression Spring 2 is the medium 8kg spring with a ratchet built in. Choose this stainless tension spring when you want a plain, hook-on spring with a limiter and no moving parts.
Pairs well with
Nemtek 1.6mm aluminium fence wire, 1.2mm galvanised wire, our 6 line and 8 line square tube brackets, the 6 line electric fence kit, and a Nemtek Merlin Stealth M18S energizer to run the fence.
Key features
- Stainless steel spring. Stainless steel resists rust on a fence that stands in the weather all year, though no steel is proof against it.
- Built-in limiter. A stiff limiter wire stops the spring stretching past its limit, so it keeps its pull after the wire has been pulled or knocked.
- Takes up expansion and contraction. Fence wire grows in the heat and shrinks in the cold. The spring takes up that movement so the strand stays tight between the brackets.
- Loop at each end. One loop hooks onto the fence wire, the other onto the spring hook or end insulator at the bracket.
- No ratchet, no moving parts. Set the tension by hand when you make the wire off. For a spring you can re-tension with a ratchet, see the Nemtek Hybrid Compression Spring 1.
- Sold singly. Buy one to replace a stretched spring or finish a single strand. The same spring is also sold in a pack of 50 for new fences.

Questions people ask
It is a stiff wire fitted to the spring that stops the coils stretching past their limit. A coil spring pulled too far does not return to its length and loses its grip on the wire, so the limiter protects the spring and keeps the strand tight.
The maker does not state a pull rating, spring wire size or steel grade, so we do not quote them. If you need a stated tension class, the Nemtek Compression Spring 1 is rated at 5kg and the Nemtek Hybrid Compression Spring 2 at 8kg.
The maker does not state a wire size. It is a hook-on tension spring for wall-top electric fence strands. If you want a spring rated for a specific wire, the Nemtek springs are rated by wire size and type.
Hook one loop onto the fence wire and the other onto the spring hook or end insulator at the bracket. Pull the strand tight and make it off with a line clamp or ferrule. The spring then takes up the movement of the wire.
Not with this spring on its own: it has no ratchet, so you set the tension when you make the wire off. The Nemtek Hybrid Compression Spring 1 puts the spring and a ratchet in one unit that you can tighten later.
Yes. The pack of 50 is the same spring, packed for fitting out a whole fence or for installers who keep stock. This page sells one spring.
No. Alectra supplies the equipment only. An electric fence must be installed and certified by a registered electric fence installer, who issues the compliance certificate.
