ABSTRACT:
An apparatus is provided for removable support from a framed member to be hung and with the hanging wire of the framed member being upwardly deflected and tightened as though supporting the weight of the framed member. The apparatus includes an upstanding channel incorporating a single outstanding and upwardly opening hook adjacent its lower end for engaging the longitudinal mid-portion of a picture frame hanging wire and the upper portion of the channel includes a slide adjustably positionable along the channel and defining a downwardly facing, plane abutment surface normal to the longitudinal extent of the channel for downwardly abutting the upper margin of the frame from which the hanging wire is supported. The single hook may be substituted for by a pair of oppositely laterally offset hooks for use in determining the desired location of a pair of frame hanging hooks.
