the saddle member 22 the lower saddle member 24 is then slipped over the legs 30 and 32 of the square u bolt 26 so that the semi circular portions 66 abut the muffler outlet 44 the saddle member 24 is inserted so that the semi circular portions 66 are displaced with respect to the semi circular portions 60 in the saddle member 22 so that the respective legs 22a and 24a are displaced with respect to each other as shown in fig3 thereafter the nuts 38 are screwed on manually or with a power tool to develop sufficient compressive force on the muffler outlet 44 to obtain a gas tight interface connection between the muffler outlet 44 and the tailpipe 42 in view of the large tolerances that exist during the manufacture of the muffler outlet 44 and the tailpipe 42 it is necessary that any hanger clamp that is used must have components which are capable of compressing the telescoped interconnection between the outlet 44 and the tailpipe 42 by using a pair of saddle members 22 and 24 provided with respective offset semi circular portions 60 and 66 it is possible to draw up on the nuts 38 to force the saddle members toward each other to develop therebetween substantial compressive forces around the entire periphery of the muffler outlet 44 to obtain a gas tight coupling between the muffler outlet 44 and the tailpipe 42 this is possible because the saddle members 22 and 24 as the nuts 38 are drawn up do not possess any portions of construction which would interfere with the drawing up.
