A 50 pack of Nemtek Hybrid Compression Spring 2 tensioners for new fences and installers who keep stock. Each is the gold 8kg electric fence tensioner spring with Nemtek's ratchet built in, tightened with a 1/4 inch ratchet, rated for 1.2mm galvanised or stainless steel wire and 1.6mm aluminium wire. On a six or eight line fence the tensioner count adds up quickly, which is what the 50 pack is for. For one repair, the single tensioner is on its own page.
What's in the pack
- 50 Nemtek Hybrid Compression Spring 2 tensioners, black body
Same tensioner as the single
Only the quantity changes. Each unit is a medium 8kg gold stainless spring with a glass-filled nylon ratchet spindle, so you wind the strand tight with a 1/4 inch ratchet and the spring holds constant tension afterwards. Each one links to the end bobbin with a Nemtek large tail hook, so pair the 50 pack with a pack of hooks.
The spring for 1.6mm aluminium wire
Nemtek pairs the gold 8kg Hybrid Compression Spring 2 with its 1.6mm aluminium wire, so this is the pack to put with the 1000m or 500m stranded aluminium rolls or the solid aluminium alloy wire. Nemtek also rates it for up to 1.2mm galvanised and stainless steel wire. The standard 5kg silver spring with a ratchet is the Hybrid Compression Spring 1, 50 pack.
Gold is a tension class, not a grade
Gold means Nemtek's medium 8kg spring, as silver means the standard 5kg. It is not a higher grade of the same spring, and Nemtek does not limit it to any type of property or length of run.
Nylon inner, wide temperature range
The nylon inner between spring and wire stops galvanic reaction, and the body is UV stabilised plastic. Nemtek rates the unit for -40 to 80°C and 0 to 12kV, at 0.023kg each. Nemtek lists no pack size, so the 50 pack is our quantity.
