What is "slatwall"

Slatwall (also known as slotwall) is a building material used in shopfitting for wall coverings or display fixtures. It consists of panels, usually 4 ft. by 8 ft., made with horizontal grooves that are configured to accept a variety of merchandising accessories. The panels are typically made from medium-density fiberboard (MDF), with a finish such as melamine paper pressed or laminated onto one or both sides. Grooves are then machined into the board and painted or fitted with plastic or aluminum inserts.
