In the world of web slings, no sling is regarded more highly and respected as tougher than the Tuff-Edge II line of slings from Lift-All. The offer twice the strength after being subject to abrasion, and twice the resistance to edge cutting that normal yellow slings offer. This is backed up by thorough testing using Federal Test Method 191A. It's not just tough, but safe too! Red inner core yarns serve as a warning system so you know when your sling is damaged beyond a serviceable condition. A Tuff-Tag provides required OSHA information for the life of the sling (not just the life of the tag). To top it off, these slings are easy to identify...silver body, blue edges and a blue center stripe.
