Trimmer (construction)

In [[light-frame construction]], a '''trimmer''' is a timber or metal beam (joist) used to create an opening around a stairwell, skylight, chimney, and the like. Trimmers are installed parallel to the primary floor or ceiling joists and support [[Framing (construction)#Lintels (headers)|headers]], which run perpendicular to the primary joists.<ref>{{Cite web|url=https://www.graphicstandards.com/gs/landing.html#searchQuery?searchQueryString=trimmer|title=Architectural Graphic Standards Online|access-date=2016-07-25}}</ref><ref>{{Cite book|title = Building Construction Illustrated, 3rd Edition|last = Ching|first = Francis D.
