ABSTRACT:
A fire escape device having an elongated flexible element terminating in an end anchorable to a building structure and having a length sufficient to reach a lower, safe support level. Detachably mounted on the flexible element for longitudinal movement therealong is a slide and sling assembly including a clamp arranged for clampingly engaging the flexible element in such a manner as to form a loop therein. By this arrangement, the rate of descent of a person using the device can be controlled not only by tightening and untightening the clamp itself, but also by pressure applied to the loose end of the flexible element by the user or by any other person below.
