Our newest Escape Descender for our EGRESS escape ropes. Allows for quick deployment and adjustment before the bail out. Rotating Handle provides exceptional control. Double Stop for safety. The D2 is a true panic stop device rather than a panic brake device. The difference is that once the panic brake is activated, no other force must be applied to the device. A panic brake style device requires a force input to continue the braking function. Also works well as an emergency lowering device and ascender.
