Nylon is the most commonly used sling because of its general purpose as a synthetic web sling. Nylon Slings are lightweight, flexible, and relatively soft.  They are suitable in applications were minimal damage to the load’s surface finish is important. Nylon Slings are adaptable for use as a vertical, choker, or basket hitch used in rigging, general purpose overhead lifting, crane hoisting, and material handling.

Type 4 sling is often referred to as the twisted eye & eye (TEE) sling. Twisted eye & eye nylon lifting slings have eyes on each end and are identical to the type 3 sling, but the loops have a twisted design, which creates a right angle to the body of the sling. This twist allows the sling to fit more snug against crane hooks. When using the basket hitch arrangement, the two rotated eyes join compactly. While this twisted eye sling works well with a basket hitch and vertical hitch, it’s most suitable for use with choker hitches.
