Southern Wire Fastlock is one of the world's best farm fence. Using the revolutionary new square knot to lock high tensile vertical and horizontal wires securely together, this 100% heavy galvanised fence will remain intact through the most difficult terrain, extreme temperatures and heavy stock pressure.

The square knot is a stronger, more compact version of the old ring joint type fencing, which eliminates the annoying ring-ping and moving vertical wires that plague lesser fences. With clean, snag free rolls, Fastlock is easy to use with a knot that can be simply removed with a snip from a pair of pliers.

Fastlock is manufactured to Toughline specification, having a 2.80mm top and bottom wire. These three features make Fastlock a product of choice for farmers and contractors around Australia.

Southern Wire Fastlock provides:

  • Longevity - Manufactured in Australia using high quality, heavy galvanised wire.

  • Strength - Fastlock knot to minimise the risk of the vertical wire slipping.

  • Stability - Single picket wire to provide long-lasting vertical integrity.

  • Durability - 2.80mm top and bottom wires to manage heavy stock pressure.
