450 - Glynn Johnson

Medium-duty, surface mounted.

The track Glynn Johnson 450 Series surface mounts to the door and the arm mounts to the door stop. Track mounting allows the arm to slide creating a moving pivot point.

Similar to the Glynn Johnson 90 Series, only Medium-duty.

• 450S = Stop Only
• 450H = Stop plus Hold Open
• 450F = Stop plus Friction Hold Open
• Available in standard architectural finishes
• Less expensive powder coated finishes also available
• UL Listed
• 1-year warranty

Glynn Johnson designed the 450 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 450 Series overhead stops are sized. This means different models are used with different door widths.

• 18-23'' - models 451S, 451H, 451F
• 23-27'' - models 452S, 452H, 452F
• 27-33'' - models 453S, 453H, 453F
• 33-39'' - models 454S, 454H, 454F
• 39-45'' - models 455S, 455H, 455F

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.

Quick Tip

Both the door and the frame should be reinforced where the unit mounts. With metal doors and frames, a 1/4'' steel plate is welded to the backside. This area must be drilled and tapped for the mounting bolts. When possible, a more secure installation can be accomplished by using through bolts.
