seeking clarification on mounting options for #4 commercial door closer

Hi,

I'm looking to replace a door closer on an all steel (door and jamb) exterior entrance. I believe the description of what I currently have is "parallel, door & under jamb-mounted". I believe the #4 size is appropriate for my situation, but I want to be sure that the closer comes with mounting hardware that would support the same application configuration as shown in my photos. As there is a window immediately above the door I don't have a lot of jamb space atop the door to work with and would like to mount the new closing arm under the door jamb again. I understand that I may have to drill new holes... not worried about that.  is in reference to your part #79-264 (#4, Commercial Door Closer, Bronze). I haven't seen a reply come through yet, so I re-read the question I'd posted and realized I might not have provided complete info.

Thanks,

Luke

Thanks. To clarify, the inclusion of screws was not my concern. I was primarily wondering about the inclusion of an under-jamb mounting bracket (similar to the triangular bracket shown in my photo).. as well as attempting to understand whether the 79-264 part description of "top jamb or parallel arm installation" described the same type of installation I currently have. I've done some other reading/research and think I'll be able to figure it out.
