DoForce 1 round slings have printed load capacity numbers. In addition, these round slings have woven-in ton strips, one strip per ton of load capacity. Each round sling is abrasion-resistant and therefore dirt-repellent thanks to the special impregnation. The load-bearing element of a DoForce 1 round sling is endless, high-quality polyester fiber strands. The load capacity of the round slings increases with the number of these fiber strands.
