Swing Functions:
• Closing speeds are controlled by two non-critical adjustment valves. Sweep area is from 105° to 20°. Latch area is from 20 to 0.
• A mechanical backcheck slows down the door prior to contact with the positive stop.

Degree of Opening:
• An integral positive stop limits door swing to 105°. The purpose of this stop is to prevent the door from hitting a wall or other architectural feature

Header/Overhead Door Stops:

• An auxiliary stop(Header Stop) should always be installed in conjunction with the closer to prevent a door from swinging past the required stop point.
• Door hardware may require that a door swing to only 85 degrees to prevent exterior handles from hitting a wall. Similarly, hardware on the push side of the door may require that the door swing further than 90° degrees to clear the opening of protruding hardware
• Stop used for single acting applications
