ArborMAX single eye slings with X-Rigging beast rigging ring. Ring slings are all the rage in tree rigging today. Rigging rings were originally developed by arborist David Driver (known as the X-man), as a simple concept that allows for a multitude of applications. Single eye ring slings are usually used for lowering line redirects, but other uses are numerous. These ring slings are spliced with Samson Tenex TEC rope. Tenex TEC rope provides excellent breaking strength for your rigging job and is lighter than double braid rope. Samson Tenex TEC is also coated for maximum resistance to abrasion. Single eye ring slings should only be used as redirects in a rigging system as they do not provide enough of a bend radius to be used as a primary rigging point, especially when dealing with significant weight.
