Door closers may have a stop or limitation on the degrees of swing that a door will open. The purpose of this stop is to prevent the door from hitting a wall or other architectural features. Typical swings are at 90° or 105°
Door Hardware may require that a door swing to only 85° to prevent exterior trim from hitting a wall. Similarly, hardware on the push side of the door may require that the door swing further than 90° to clear the opening of protruding hardware.
For closers that do not have a dead stop, you may need to utilize an overhead holder/stop to prevent a door from swinging past the required stop point.
