Concealed door closers are found in most commercial building and serve a useful purpose in controlling the closure of exterior entrance doors. The correct placement and installation of a door closer presents an arduous challenge for an installer who is often faced with uneven surfaces upon an active construction site. The related art relies upon the use of plumb bobs attached to upper door frame components and measuring implements placed upon ground surfaces. The task is so difficult that special training is required and specialist in the art are often employed install door closers. The presently disclosed embodiments comprise a jig system allowing for one or two door closers to be correctly positioned without the use of external or hand held measuring implements. An optional laser mounting system vitiates the need to attach lasers to door closer spindles.
