Glynn Johnson 411H-US32DAlso known as: 411HUS32D
The Glynn Johnson 411H-US32D medium duty concealed overhead door holder/stop offers effective door control and a low-profile design. Each model is constructed so that the channel is encased in the door and the jamb bracket is mortised in the frame. When the door is open, the arm and jamb bracket are visible. Conversely, when the door is in the closed position, theentire holder is completely concealed.
These versatile models can be used with most surface-applied door closers. The provided templates allow for variable mounting positions, ranging from 85 to 110 of opening. These templates are designed for installation in almost all types of doors, including doors with conventional butt-type hinges or specialty hinges.
The 411H-US32D Hold-Open models provide a convenient method of holding the door open at a predetermined position for short or long periods of time, permitting an unobstructed traffic flow. The Hold-Open tension can be adjusted using an allen wrench through the end of the slider located in the channel mounted in the top of the door.
The unit features a rugged, automatic Hold-Open mechanism activated when the door is opened to a preset angle. Each model meets the 250,000 test cycles required for Grade 1 classification. The Hold-Open feature is not selectable, so the door is always held open. The 411H-US32D features a satin stainless steel finish and is designed for door openings ranging from 18" to 23".
