Made from 1-inch (25-mm) mil-spec tubular web, these runners have a loop sewn at each end. Available in four sizes that have proven popular for rescue operations, the large size works well for tying a mariner’s knot. The minimum breaking strength end to end is 19 kN (4,200 lbf). About CMC Rescue Web Gear CMC Rescue sewn web products reflect many years of manufacturing experience and designs based on field use, rescues and testing. Lightweight yet durable, our tubular web delivers a high strength-to-weight ratio. Each product is sewn in our own California manufacturing facility with contrasting color thread for ease of inspection. We build CMC Rescue Web Gear as if we were going to use it ourselves – and we do.
