ABSTRACT:
A safety support and rescue clamp for use on building structures for supporting personnel and equipment on wall faces of buildings. The clamp is characterized in that it is receivable into an elongated vertical, channel-like slotted track of the type affixed in the wall of a high-rise building. A pivotal pawl of the clamp bridges between side walls of the slot and locks rotationally within the track to serve as positive anchor means for overcoming a weight-derived, downwardly-directed force vector impressed upon a lever attached to the pawl and extending outwardly from the track.
