One Nemtek Hybrid Compression Spring 2, the gold 8kg spring with a built-in ratchet, sold singly for repairs or a single line. It is two parts of an electric fence tensioner in one: the compression spring that keeps a constant pull on the strand, and a ratchet spindle you tighten with a 1/4 inch ratchet to take up slack. Gold is Nemtek's medium 8kg tension class, rated for 1.2mm galvanised and stainless steel wire and for 1.6mm aluminium wire. For a new fence, the 50 pack is on its own page.

What you get

  • 1 Nemtek Hybrid Compression Spring 2, black body

Spring and ratchet in one

With a plain compression spring you pull the wire tight by hand and fix it. The hybrid adds a glass-filled nylon spindle that you turn with a 1/4 inch ratchet, so you wind the strand tight and can come back later to take up slack. The spring then holds constant tension between visits. Link it to the end bobbin with a Nemtek large tail hook.

Which wire it suits

Nemtek rates the Hybrid Compression Spring 2 for up to 1.2mm galvanised and stainless steel wire and up to 1.6mm aluminium wire, and it is the spring Nemtek pairs with its 1.6mm aluminium wire: the 500m and 1000m stranded rolls and the solid aluminium alloy wire. It also suits 1.2mm galvanised and 1.2mm stainless steel wire where you want more pull than the 5kg silver spring.

Gold is a tension class, not a grade

Gold is not a higher grade of the same spring. It is Nemtek's colour code for the medium 8kg spring, as silver is for the standard 5kg. The 5kg version with a ratchet is the Hybrid Compression Spring 1.

Nylon inner, wide temperature range

The nylon inner between spring and wire stops galvanic reaction. Nemtek rates the unit for -40 to 80°C and fence voltages from 0 to 12kV, and lists its weight at 0.023kg.

Questions people ask
What tool do I need to tension it?

A 1/4 inch ratchet. The spindle is built into the spring, so there is no separate tensioner to buy.

What is the difference between gold and silver?

Tension class. Gold is Nemtek's medium 8kg spring; silver is the standard 5kg spring. Gold is not a higher grade of the same part.

Can I use it on 1.6mm aluminium wire?

Yes. Nemtek rates it for up to 1.6mm aluminium wire and pairs it with its 1.6mm aluminium fence wire.

Can I re-tension the wire later?

Yes. Turn the spindle with the 1/4 inch ratchet to take up slack.

Do I still need the large tail hook?

The Nemtek large tail hook is the quick link between a Nemtek tensioner and a flat bar or round bar insulator. It is sold separately in a pack of 50.

Do I need an installer to buy this?

No, anyone can buy it. The fence itself must be installed and certified by a registered electric fence installer. Alectra supplies the equipment only.

Need it fitted? Alectra Solutions supplies product only. Ask the branch and we will point you to installers in Pretoria.
