From Wikipedia, the free encyclopedia
Jump to: navigation, search

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 floor or ceiling joists and support perpendicular headers.

It can also refer to a jack stud that supports a header above a window or door opening.

Traditionally, a stud which was less than full length was sometimes referred to as a cripple.[1][2][3]
