Kite World has been making these spikes, in Aalborg, Denmark since 2010.
Design and info
- The straps have been used in winds upto 25m/s (50knots).
- The strap is removable from the spike.
This allows for the strap to be used when the ground is too soft for the spiral spike, so you can use it on a pole or a car (wheel / tow hook). It is also very useful if you have something that needs to be strapped up : )
- The length of the strap is the best combination of length to working safety.
- They are designed for quick releasing.
