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 or 180 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.
