  • Patent number: 6966531
    Abstract: There is an anchor for securing a working line (54) to a structure. The anchor includes a sole plate (2) with an attachment (19) for the working line (54). There is at least one friction plate (5) and a connector strap (4). In use of the anchor the sole plate (2) and friction plate (5) are located against respective opposite sides of a rafter (3) of the structure and are linked together by the strap (4) in a manner such that the working line load on the sole plate (2) generates a clamping force between the sole plate (2) and the friction plate (5). This force resists movement of the anchor by gripping only the outside of the rafter (3).
