First and second elongated members are slidable along each other to form a beam of variable length to span the top surface of a structure on which a worker is positioned. Clamping surfaces extend from the ends of the beam to engage the sides of the structure. A lever pivotally mounted on the first elongated member is connected through a link to the second elongated member to shorten the beam and urge the clamping surfaces against the structure. A worker\s safety line may be attached to the device such that the lever is locked relative to the first elonga...
A mounting device for securing a safety line to a structure on which a worker is positioned, comprising: a first elongated member; a second elongated member, substantially coaxial with the first elongated member, having a side portion thereof slidably movable along a side portion of the first elongated member such that the elongated members together span the structure on which the worker is positioned; clamping means mounted on the distal ends of the first and second elongated members adapted for engaging the structure; a lever pivotally mounted on the f...
