"The Dutch Buckle is specifically designed to replace the marlin spike hitch with a light, faster, and safer method of connecting the whoopie sling to the hammock suspension tree straps. Once on the buckle, the whoopie sling can be easily adjusted and won’t slip off. The buckle is completely adjustable so you can quickly slide it up or down to accommodate a wide variety of tree sizes.


As an added feature the Dutch buckle has a retention shock cord and latch method to keep your tree straps nice and neat when not deployed.


Weight: 10 grams.

Accommodate 1″ (25mm) webbing."


The above wording is straight from Dutch, and his team.
