closer are set up for ranges of door width and assume normal
operating conditions. If a door is of exceptional height, weight,
special construction, or if drafts and air pressure differ entials exist,
increased closer power should be considered.

Door thickness may be a factor. A concealed-in-the-door closer

mm) thick or a wood door under 1-3/4˝ (44 mm). Exceptionally For purposes of handing door closers, right hand reverse bevel and
