mechanism operatively attached thereto and where another end of the cylinder closing mechanism is attached to a door frame
through a bracket, said device comprising:
(a) a hold-open apparatus having a first end, a second end, and an interconnecting central portion, wherein said apparatus
second end is adapted to engage an end of a cylinder of the cylinder closing mechanism when the door has been opened to at
least a predetermined degree to maintain the door in an open position; and
(b) an adapter having a male portion which operatively connects said cylinder closing mechanism end to the bracket, and a
female portion, wherein said apparatus first end is operatively connected to said adapter female portion; or
(c) a spring is connected to said apparatus first end which biases the apparatus towards the cylinder closing mechanism, wherein
the spring will cause the apparatus second end to automatically engage said cylinder end when the predetermined angle has
been reached, and wherein said apparatus first end is operatively connected to the bracket in an aperture separate from an
aperture which connects the cylinder closing mechanism to the door frame.
