The 3M™ and DEUS™ Escape and Rescue System is available with two controlled descent device options – the 3300 device and the 3700 device. The 3300 device allows for rescue from heights up to 350 feet, at a descent rate of 3 meters/second (9.8 feet/second), making it ideally suited for situations where time is of the essence. The 3700 device has been third-party tested and certified to the ANSI standard and offers users a descent rate of 2 meters/second (6.6 feet/second) from heights up to 590 feet.
