Beaver round slings are an all-purpose lifting sling, enabling a strong and non-damaging lift of its load. They are extremely lightweight and flexible in multiple directions, allowing easy and quick manipulation even when fragile loads are being lifted. These round slings are a continuous loop made from polyester yarn encased in a sleeve of polyester, or nylon fabric. The sleeve is constructed so it protects the internal rows of yarn filament and keeps them in a parallel formation at all times. These slings are manufactured to AS 4497.1, and a test certificate is available upon request.

The yarn fibre core is free to spread out 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.
