The ideal fix point for concretingThe fix point "concret anchor" is ideal to fabricate a fixpoint for slacklines. The foot can be concreting in a stabil subgrade. The rounddisc with the screw thread eyebolt has to be plan with the subgrade. In the screw thread eyebolt the slackline is fixed and put over a A rack. So you get the right height for slackling. The screw thread can be screwed out too and does not disturb for example by mowing the lawn.
