Abstract
Abstract An adjustable magnetic door holder comprises an electromagnetic unit and an adjustable strike support which includes a base and an armature or strike plate. The strike plate is adjustably coupled to the base by a ball and socket joint carried by a cylindrical member supported for limited angular movement and axial translation relative to the base whereby wide variation of adjustment between the strike plate and base may be attained to facilitate precise alignment of the strike plate with the electromagnetic unit.
