410 - Glynn Johnson
The Glynn Johnson 410 Series is completely concealed when the door is closed. The track mortises into the top of the door and the arm bracket mortises into the frame. Similar to the Glynn Johnson 100 Series, only Medium-duty.
Glynn Johnson designed the 410 Series to be installed on doors opening between 85 and 110 degrees. It is available as a stop only (S), stop with hold open (H), or stop with friction hold open (F). The H version has a control knob used to turn the hold open function on and off. During installation, the hold open position is set and the same position is used each time. Once set, the door always holds open in that same position. The F version, Friction Hold Open, allows for multi-point hold open positions. This means you can open the door to any position and let go and the door will hold in place. To order, determine your door width (see listing below). Next, decide if you need stop only or one of the hold open options. The Glynn Johnson 410 Series overhead stops are sized. This means different models are used with different door widths.
Since a standard commercial door is 36'' wide a Size 4 stop would be used The next step is to decide if you need a stop only, or a stop + the hold open feature. The designation for stop only is "S" and for hold open it is "H". Below is a chart for both series showing size and feature designation.
