Glynn Johnson 412H Concealed Overhead Door Stop / Holder 23-1/16" - 27" Door

Glynn-Johnson 410 series holders and stops are designed for medium- to light-duty applications. They’re ideal for openings that are subject to normal activity, providing protection for the door, frame, hinges and surrounding walls or obstructions.

All models incorporate the popular channel/slide-arm design and offset jamb brackets. This improved design allows for simple field modification of functions, should user requirements change.

Hold-Openmodels 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.

These models feature 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

Glynn-Johnson 410 seriesholders and stops offer effective door control and a low-profile design.

Each model is constructed so that the channel is encased in the  oor 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, the entire 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 Degree to 110 Degree of opening. These templates are designed for installation in almost all types of doors, including doors with conventional butt-type hinges or specialty hinges.
