The best door control device is one that operates overhead, with an arm functioning from the jamb to the top of the door.
When the door stopping or hold-open does not exceed 110°, these devices are more efficient than floor or wall-mounted stops.
These templates are designed for installation in almost all types of doors, including doors with conventional butt-type hinges or specialty hinges.
Glynn-Johnson overhead stops are designed to protect door closers from violent openings, and are simple to install.
