70 79 - Glynn Johnson

70 Series = Heavy Duty
79 Series = Extra Heavy Duty

Use the 70 Series for most commercial application. The 79 Series is used for extra-heavy doors or abusive applications.

Both Series have the same features in common, the 79 Series is simply made from heavier materials.

• 70S and 79S = Stop Only
• 70H and 79H = Stop plus Hold Open
• Available in standard architectural finishes
• Also available in less expensive sprayed finishes
• UL Listed
• 1-year warranty

Ordering overhead stops is fairly simple if you follow a few basic rules.

First, if a door closer is also being used, pay attention it's mounting. You don't want the arm of the closer to interfere with the arm of the overhead stop. This rarely is the case, but always be on the lookout for potential conflicts with hardware.

Secondly, overhead stops are sized. This means different models are used for different door widths. The ''size'' is added to the series number.

• 23-27'' - model 702 or 792
• 27-33'' - model 703 or 793
• 33-39'' - model 704 or 794
• 39-45'' - model 705 or 795
• 45-51'' - model 706 or 796

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

You can order overhead stops in architectural finishes.  You may also order them with "sprayed finishes.  These finishes are applied much the same way a car is painted and are substantially less expensive.  Sprayed finishes are noted by "SP", such as SP3, SP10, etc.
