You can expect longer sling life and lower overall costs when you switch to Tuff-Edge II slings. Resistance to the two properties that can rapidly degrade webbing, abrasion and edge cutting, is greatly improved with the use of our Tuff-Edge II webbing. Using Federal Test Method 191A, Tuff-Edge II webbing was tested against standard yellow polyester webbing. After being subjected to the same number of hex bar abrasion cycles, the Tuff-Edge II webbing, with its' special silver treatment, achieved average break strengths that were twice that of the standard yellow webbing! In a test developed specifically to measure edge cutting properties, the cut depth on the Tuff-Edge II webbing with special polymer edge yarns cut less than half the depth of the standard yellow polyester without the special edge yarns. Although you should always pad and protect synthetic slings from load edges, normal wear and tear should be greatly reduced when using Tuff-Edge II, giving you greater sling life and reduced sling costs.
