Tightlock Fencing
Cyclone made the world's first deer fence in 1967, designed for maximum durability.
The fence consists of line, stay and knot wires. Line wires are spaced for different stock types to provide maximum strength and security at the most needed points of contact. They are continuous in length and made from high tensile wire. The stay wires (vertical) are continuous in length. They combine with the knots and tension curves to create overall rigidity and elasticity. The load of any impact will spread and dissipate over the full fence height and for some distance on either side.
Economical galvanised products are available and offer an alternative that can be confidently used where corrosive elements are low. A select range is available in this coating.
| PROPERTIES | BENEFITS |
|---|---|
| Independent knots | Increase structural strength of the fence Allow wire to follow contours |
| Fabricated | Faster to erect Less posts required Lower total fence cost than wire and batten |
| Tension curves | Easy to strain Allows for impact to dissipate over the fence and return to original condition |
| TYPE | APPLICATION |
|---|---|
| FAWN | Used in deer fawning paddocks due to the tighter 240 mm stay wire combined with the 89 mm line wire prevents new born fawns from slipping through the fence. |
| DEER | 1900 mm is the standard height. 1550 mm is used with a top wire to make up the 1900 mm height. A 150 mm stay wire is often used for additional security on boundary fence and raceways compared to a 300 mm stay for internal fence and sometimes used for boundary as an economical alternative. Used for deer and ostriches. |
| TOP UP | Designed to make the extra height on top of a standard fence rather than replacing the entire fence. Used for deer and ostriches. |
| FIELD | Regional differences dicatate the different line wires and total heights. Combinations with barbed wires or electric wires complete the barrier for stock. Used in high stock pressure applications for cattle, sheep, goats and pigs. |
