Lowest weight per capacity reduces risk of back and other injuries to riggers.. Low stretch (1% at rated capacity) reduces elastic bounce for better load control - allows for use in most low headroom situations - reduces sling and load abrasion.. Aramid load yarns allow sling use up to 350 Degrees F versus 200 Degrees F for other synthetics.. Light weight and compact size promotes speedier rigging, transport and storage when compared to any other type of sling.
