Factor of safety for webbing 1:7 The colour combination as shown in the chart is a mere indicator, however the colour may change subject to availability of raw materials Features Soft, supple, and light in weight, easy to handle. Internationally identifiable colour code, SWL shown on slings and also shown by the way of woven stripes i.e. each black stripe for each ton. Being endless, wears evenly as there is no single point use. Ideally suited for lifting smooth, polished or coated objects. Conforms to B. S. 6668 Part 2 and Indian standards. Zebra Round Slings are light weight compared to the working load ratio and being Polyester do not rust or corrode as in metal slings.
