Abstract
A system for adjusting a junction box, to be recessed with respect to a ceiling, between a minimum ceiling thickness and a maximum ceiling thickness, utilizes a pair of hanger-bar-to-box-attachment-devices that are attached to both the junction box and to a pair of hanger-bars. The pair of hanger-bar-to-box-attachment-devices are attached to the junction box in an adjustable manner that is vertically slidable and lockable along a finite vertical path. And the pair of hanger-bar-to-box-attachment-devices that are also attached to the pair of hanger-bars, are adjustable in a horizontally slidable and lockable manner along a finite horizontal path, defined by a length of the pair of hanger-bars. The junction box may also have a set of height-markings on its exterior to facilitate adjusting the junction box to a desired height with respect to a given ceiling.
