Abstract: An apparatus for securely joining ropes for rope suspension or payload tie down. The apparatus includes a two substantially identical channel assemblies configured having a first bend to form a rope groove on one end and a second bend to form a cam channel on the other end, the cam channel having a rivet hole and a pin therethrough to enable a cam to rotate therein, and an attachment mechanism to secure the channel assemblies back-to-back thereto. By opening the cam of either assembly, a rope may be threaded through the rope grove, then again on the opposite assembly. The rope can be pulled from its end away from the assemblies to tighten prior to closing the cam(s) upon the ropes. The rope can further be secured by continuing to pull after the cam has been closed, or by using an optional tightening mechanism and method.

Abstract: A device for measuring and marking lines and points on a steel I-beam includes a rib for contacting the outside of an I-beam flange along a line opposite the center of the beam web, a measuring blade that rests on the beam web and measures distances from the outside of the flange, and a bridge for connecting the measuring blade to the rib in a way in which the measuring blade is held perpendicular to the flange. The device marks I-beams faster and more accurately that was possible using prior art tools and techniques.
