finger joint board

Finger-joints are used to join short pieces of wood together to form pieces of greater length. The joint is composed of several meshing wedges or “fingers” of wood in two adjacent pieces and is held together with structural adhesives.
Finger-joined lumber is used for both structural and non-structural products. Structural product uses include vertical studs and horizontal plates in residential platform-frame construction and the manufacturing of cross-laminated timber and glue-laminated timber. Non-structural uses include moulding and trim.
