This wiggle wire and channel bundle is the most economical one I have found. But it’s quality material! Three layers of 6 mil plastic was easy to secure with a single wiggle wire per channel. Two layers of plastic will fit with two wiggle wires as well, if you need to have a section of plastic that can be removed easily. It’s nice that they also paint a blue strip on two sections of each wire because black wire laying on the ground blends in very easy.
The channels secured easily to the sidewall boards, and they bend over arches with very little force. If you have no experience with wiggle wire, this is probably the best set to start with, as it is self explanatory but includes instructions if you happen to need them.
I am already planning on buying more of these bundles for my next two high tunnel projects.
Highly recommend this bundle
