In principle the clamp is simple. Itconsists of a wedge grooved on one side and smooth onthe other, which fits into a tapered sleeve with internalgrooves on one side. These grooves on the wedge andsleeve when mated form for the strands a pair of channelswhich are gradually reduced in section as the wedge entersthe sleeve. To apply the clamp the span or guy strand is run throughthe sleeve, thence around the pole or through the eye ofthe anchor and back through the sleeve. The wedge is theninserted in the sleeve, and as it is driven tight it wedges thewire securely, the two sections of strand filling the double groove in the sleeve and wedge permits clamp-.

The time required to applythe clamp after the slack has been taken up in the strand isalmost negligible, most of it being consumed in attaching a short section of wire from the strand and giving this a fewturns around the guy to make the connection neat in ap-pearance. Another advantage which developed through actual serv-ice on the Peoria Railway Companys lines is the ease withwhich sags may be taken up in new line while the poles areassuming a permanent set. This is accomplished by ap-plying a come-along and small block and fall between thespan wire and the pole and after the slack is taken up thewedge is removed, thus allowing the slack to pass throught
