A flat sling that is properly stored can deliver years of reliable service. A sling that is stored improperly can degrade silently—losing strength through abrasive wear, chemical exposure, UV radiation, and mildew growth without any visible warning.
Selecting the right flat sling width is a balancing act between two critical factors: load capacity and surface pressure. A wider sling provides higher working load limits and distributes weight over a larger area, reducing the risk of crushing or marring delicate loads.
A flat sling can look perfectly serviceable on the surface while hiding damage that compromises its load-bearing capacity. According to ASME B30.9, synthetic web slings must be removed from service immediately when specific damage conditions are present—including holes, tears, cuts, or snags that expose load-bearing fibers, and broken or worn stitching in load-bearing splices .
Choosing between an eye & eye flat sling and an endless flat sling is not a matter of one being stronger—both offer identical rated capacities for a given size and can be used in vertical, choker, and basket hitches .
