Good point on the tool aspect but he didn't say these were all tools i don't think. It looks an awful lot like cable clamps we used to hang alarm cables from pole to pole and clamped the steel twisted cable that was jacketed on one side as part of the alarm cable to a bare twisted steel support cable that ran between poles. that way the support cable bore the weight, not that alarm cable. those we used were smaller though and only one or two bolts. Your description sounds feasible enough but having three bolts to tighten and loosen for that purpose seem slow and awkward to me.
