half tube segment parallel to the ground the holes 65 and 66 are offset with respect to vertical thus the nails inserted through the holes and into post 64 are not likely to be in the same grain of the post in fig1 and 11 there is shown another preferred embodiment of insulator connector 70 that is particularly suited for use with the clips shown in fig1 4 connector 70 includes a flange 71 with a boss 72 projecting from one face 71a thereof and with oppositely extending fingers 73 and 74 spaced outwardly on opposite face 71b a groove 75 extends between the fingers and the fingers have tip ends 76 and 77 respectively spaced from the flange by bridge members 78 and 79 each bridge member is grooved so that a taut wire w will extend straight across the bridge members between the flange and the fingers boss 72 has a hole 80 extending therethrough parallel to the groove 75 the insulator connector 70 is preferably made of a non conductive plastic or a suitable rubberized material in use a taut wire positioned in groove 75 and the connector 70 is rotated a quarter turn clockwise as viewed in fig1 and 11 so that finger 73 extends upwardly and finger 74 extends downwardly the hole 80 then extends transversely to the electrified wire w the boss 72 is positioned between the ears 16 and 17 of the clip 10 that is subsequently or previously nailed to a post such that the end 72a of the boss engages or is closely adjacent to the front face 20 of the clip the.
