ABSTRACT:
The invention pertains to apparatus for gauging the relative relationship between angular construction members, and particularly pertains to apparatus for measuring stub angle supports used with electrical transmission towers. The apparatus consists of a pair of threaded shafts each including a radial shoulder and a nut wherein each shaft may be received within corresponding holes formed in the planar portions of the angular member to be measured. The shafts are axially bored to slidably receive an anchor shaft having a measuring tape anchor defined thereon, the anchors of the pair of anchor shafts adapted to engage for diagonal measurements, and keying means defined on the anchor shafts and the associated threaded shaft prevent rotation of these components when the tape anchor is disposed adjacent the threaded shaft end.
