Lift America S152074 4' Poly Web Sling Endless, 9800/12200/24400 Lbs Cap
Polyester web slings are used primarily in conditions where acid is present and minimum stretch is desired. Polyester is unaffected by common acids and bleaching agents, but the material is unsuitable for use in conditions where concentrated sulfuric acid and alkaline is present. Polyester is also unsuitable in locations where temperatures exceed 194°F. Stretch of a polyester web sling at rated capacity is approximately 3%.
