ABSTRACT:
An adjustment apparatus which is capable of selectively securing to elongated members in a predetermined positional relationship includes a housing member having an eyebolt slidably positioned within a through aperture disposed longitudinally within a housing member; the eye portion of the eyebolt has a pivotal pin disposed therein affixing it to a T-bracket disposed proximate one end of the housing member. A sensing rod is disposed in a through aperture provided proximate the other end of the housing member which is permitted to flex. The eyebolt extending through the housing member is adapted to receive a threaded knob thereon and tightening the threaded knob simultaneously secures the housing member and sensing rod in a fixed position.
