Abstract: A measuring tape anchorage device can be secured to a ground surface or pavement surface to facilitate the taking of distance measurements, e.g. at automobile accident scenes or for surveying activities. The anchorage device includes an anchorage block having a swivel connection to the sub-surface, and two cylindrical mandrel elements spaced from one end of the anchorage block, so that a portion of the tape can be looped around one of the cylindrical elements and then curled over the other cylindrical element before extending away from the anchorage block. Pulling forces on the tape cause the cylindrical elements to be drawn together so as to increase the grip force of the cylindrical elements on the tape.
