ABSTRACT:
An armature assembly for use with an electromagnetic door holder has a ball stud pivotably connected at one end to a mounting bracket and at the other end to an armature plate. The mounting bracket is mounted on a first structural member, a mounting body is secured to the bracket and connects with the ball stud, and the armature plate coacts with and is held against an electromagnet which is mounted on a second structural member. The pivotable attachments at both ends of the ball stud provide an almost universal adjustability to the armature assembly and, thus, accomodate complex misalignments between the first and second structural surfaces.
