Trimmer (construction)

From Wikipedia, the free encyclopedia

In light-frame construction, a trimmer is a timber or metal beam (joist) that is installed perpendicular to floor or ceiling joists in order to allow an opening, such as a stairwell or dormer, to be formed.

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]
