1. Will the steel screw kill the tree?

No, it will not kill the tree. The treebracket is made from stainless steel and will not corrode inside the tree.A screw or large nail is the preferred way of attaching things to trees. In fact members of various green movements around the world in an anti-logging practise known as tree spiking. Metal spikes are driven into areas of the tree that loggers would be likely to saw through. The intent is to discourage logging due to the damage to the saws made possible by the embedded steel rods.

2. Does the treebracket come supplied with the plastic insulator ?

The purchase of the treebracket doesn't include the plastic steel picket insulator. The insulators can be purchased from all rural supply shops or online. There are many brands on the market and they are inexpensive. The treebracket will accommodate all common brands.

Highly recommended is the Gallagher steel picket insulator; due to its chunky design and large plastic pins it's much easier to use and is made of high quality plastic giving it good strength and durability.

3. Can the Treebracket be used for barbed wire fencing?

Yes , attach the barbed wire to the treebracket in the same way by using a steel picket insulator. In fact most fencing wires and electric strip grazing tapes can be attached to the tree in the this manner.

4. Will a fallen branch on the electric fence short out the electric current?

No, this is very unlikely. Modern electric fences are able to deliver adequate electric current with multiple branches, grasses and other vegetation contacting the wire. Only if the fencing wire is pressed directly into the ground would significant current loss occur. However if this was to occur it would mean that the whole fence has most likely collapsed and it would not matter if the fence was electric or barbed, in this event the stock would simply walk over it.

5. Is a pilot hole necessary?

Usually drilling a pilot hole is not required . Due to the hex-head on the treebracket, significant torque can be applied to the treebracket and it can be screwed into most timber to the required depth with little effort. However extremely hard timber may require the drilling of a pilot hole to reduce the screwing torque required. Also tree stems that are less than 50mm in diameter may require a pilot hole to allow room for the treebracket to avoid any stem splitting.

6. How much tensile strain should be applied to the wire ?

Because electric fencing uses an electrical pulse to discourage livestock they will keep some distance from the wire and will not push against it like they would against barbed wire. Therefore a maximum tensile strain of 15 kg force at the straining end is sufficient and is recommended. For shorter spans of 300 meters or less this means the fence can be strained by hand, for spans longer than 300 meters an inline strainer may be required. A simple way to gauge the tensile strength applied to the wire is to attach a fishing scale or baggage scale to the fencing wire and pull until the scale reads 15 kg. This will give a good indication of the recommended strain to be applied.

7. What are some general fencing tips when using treebrackets ?

Firstly pick the two ends of the fence segment that you will tie off onto and strain from. Choose the trees along that span that you will insert treebrackets into and then screw the brackets in. Tie off one end of the fencing wire and run out the wire out along the length of the span, attaching it to the brackets as you go ; but don't cut the wire at the other end until you have attached it to all the treebrackets to make sure the length of wire is long enough.  Try to choose trees that will enable the fenceline to be as straight as possible to reduce friction forces between the wire and the insulators.  The treebracket allows for articulation between the wire and the insulator so bends and zigzags can be accommodated, however sharp corners and numerous bends will significantly add to the total friction force experienced along the span of the fenceline. This situation may require a walk along the fenceline after straining to "pluck" the wire every 30 to 50 meters to allow the strain to be evenly distributed along the fencing wire. After the treebrackets are installed and the fencing wire strained then any large gaps between trees can be filled with a star picket, wooden post or pigtail. A sapling planted next to these posts will mean that in one or two years that post may be removed and be replaced by that tree and a treebracket.
