Degrees of Swing
Floor 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 feature.
Typical swings are at 90 or 105 degrees.
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.
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.
