ABSTRACT:
A support device for supporting a longitudinal member, such as a threaded rod, in a desired position with respect to the support device includes a housing adapted to receive the threaded rod, transversely within a housing aperture, and a slide axle, slideably received axially within the housing. The slide axle receives the threaded rod and is slidable within the housing to (1) a first position frictionally engaging the rod and (2) a second position disengaged from the rod so that the rod can be relatively freely moved with respect to the slide axle. The rod supporting device includes a tightening member or lock nut to secure the slide axle in a locked position whereby the rod is tightly held against a housing bearing wall defining a portion of the housing aperture. The housing bearing wall is relatively smooth so that the threaded rod is tightly held in locked position by the lock nut, while minimizing axial movement of the rod with respect to the housing.
