Are there standard hole positions?

Yes, please refer to our website under ‘order forms’.

Can I get specific holes positions?

Hole position is determined by the manufacturing process. But please ask.

What is the lowest hole position to ground level?

Preferred is 300 mm from ground level, however by inserting the post into the ground further, say 50 mm then that will lower the drip line. But caution is needed on anything closer than 150 mm from ground level as this could adversely affect performance of the post.

What post spacing’s do you recommend?

Typically 7.2m is easily achievable, with increased width also likely but will depend on crop loading. Please discuss this with our Sales Engineers.

To prevent snagging’ with bird net protection as well as a safe handling feature.

It adds significant resistance to up & down lift.

The bulge sits approx 75 mm from the bottom of the post. The post needs to be inserted 600 mm into the ground.

How do I insert the posts without damaging them?

By using post protector caps and correct installation procedure. Refer to our installation videos.

What post spacing’s do you recommend?

Cost effective alternative over the lifespan of the vineyard. And if you wish to change to organic you are already ‘on your way’.

Winged Harpoon Eco Anchor is most suited to sand / silty soil types, whereas the Standard Harpoon Eco Anchor is more suited to solid / rocky soil type.

How do I install the clip?

A simple 90 deg turn is all it takes.

Are they available in other colours?

Yes, but minimum order quantities may apply.

Does another clip colour shorten the lifespan?

As this is a new range, detail on this is not available, but some lesser level could be expected as the UV protection of coloured clips is less than the standard black.

Is the clip strong enough to withstand day to day requirements?

Yes, in the field experience over the past 6 years without incident would attest to this. We regularly batch test clips and have full supporting data available upon request.

Are the clips strong enough to withstand a water based frost protection system?

Yes the clips are capable of working well below freezing.

Yes, but not recommended.
