ABSTRACT:
Apparatus for supporting a door during processing and applying fixtures thereto prior to installing in a doorway comprises a rigid elongated frame including vertical supports at each end thereof and one or more longitudinal members interconnecting the vertical supports, each of such longitudinal members comprising a pair of telescoping tubular members and means for securing the tubular members in any desired relative positions to accommodate doors of different lengths. A pair of lateral door-supporting cross arms are individually pivotally connected to the vertical supports. A first clamp is secured to one of the cross arms near its pivotal connection to one of the vertical supports and is manually operable to clamp a door to the associated cross arm, while a second clamp is secured to the outer end of the other of the cross arms and is also manually operable to clamp a door thereto. Each of the clamps is preferably a resilient toggle joint. One of the cross arms comprises a pair of telescoping members for adjusting the position of the second clamp and means for securing such members in a plurality of desired relative axial positions to accommodate doors of different widths. A spring-biased, manually releasable latch is provided for engaging a selected slot of a cross arm indexing plate, effective to dispose an attached door in a desired position.
