Round sling is an all-purpose lifting sling, which is both high strong and non-damaging to its load. Extremely light in weight and infinitely flexible in all directions, it is easy and quick to manipulate even when awkwardly shaped or fragile loads are being lifted. Round sling is a continuous loop made from polyester yarn encased in a sleeve of polyester or Nylon fabric. The sleeve is so constructed that it protects the internal rows of yarn filament and keeps them in a parallel formation at all times. The yarn fibre core is free to spread out into a flat shape where the Round sling is in contact with its load. This provides a broad support, which cushions the load against damage and reduces slipping. The low stretch characteristics of the polyester yarn also prevent ‘load bounce’ when hoisting very heavy weights. We are the manufactuer, so buy directly from us, we will save the middle-channel costs. Wristrong Industry is the manufacturer for round slings, as well as the quality, service and prices, so there is no reason for customers to buy from the middle channels.
