"The cinch buckles are the most simplistic and easiest way to hang your hammock. These timeless devices have proven themselves in all kinds of weather. They are attached to the hammock with a 7/64th Amsteel continuous loop. A tree strap made from 1″ webbing provides all the adjustment. Just wrap your strap around the tree and fasten with your Dutch Clip. Pull the strap to get the right amount of sag and your done. No back-up knot is needed. It is highly recommended that a Ti Dutch Clip is used with this suspension as with any webbing based suspension."
The above wording is straight from Dutch, and his team.
These Cinch Buckles are for use with appropriate 25mm (1") wide Straps.
