The U-RES-Q R-Retro is a great option to be used in conjunction with a full body harness and complete fall prevention/rescue program. In the event of a fall, the U-RES-Q bag opens up and releases a 16' high strength, synthetic rescue ladder. Once deployed, the U-RES-Q can be used to climb back to the anchor point, or to stand on to allow proper blood flow and reduce the risk of Suspension Trauma (Orthostatic Intolerance). Have you ever crushed a grape with your fingers? Now you get the idea. Don't be stuck hanging around after a fall waiting to be rescued, help yourself with the U-Res-Q R-Retro.
