Whoopies and loopies and eyes . . . oh my.
Endless loops -
Loops of line, rope or webbing formed through splicing, stitching, or the use of appropriate knots and hitches. Endless loops may be used in a variety of ways in both climbing and rigging operations. Examples are Dynema Loop Runners, Nylon Loop Runners, and Tuflex Slings.
Eye Slings -
May be manufactured from many different types of rope constructions, but twelve strand hollow braids such as Tenex, and double braids are the most commonly used materials. Testing has shown that the twelve strand hollow braid constructions retain more of their strength than do double braids in an eye sling configuration.
Whoopie Slings -
Primarily manufactured from twelve strand hollow braids through the use of splicing. A whoopie sling consists of a fixed eye on one end, and an adjustable eye on the other. It should be used with the fixed eye through the adjustable eye, and gives the climber or rigger more flexibility by allowing the use of one sling on various diameters of trees.
Loopie Slings -
Primarily manufactured from twelve strand hollow braids through the use of splicing. Loopie slings are adjustable endless loop slings. They should be used in a girth hitch around the branch or trunk, with the unspliced portion passing through the spliced portion. They give the climber or rigger more flexibility by allowing the use of one sling on various diameters of trees.
Spider Legs -
Primarily manufactured from twelve strand hollow braids through the use of splicing, spider legs are long eye slings with a large single eye used to balance limbs in rigging operations. Care should be taken to use a spider leg 1/8 of an inch smaller in diameter than the rigging line it is being attached to.
