Slatwall section and assembly

Abstract

A slatwall section including a plurality of parallel frontal wall segments each extending between a first side edge portion of the slatwall section and an opposing second side edge portion of the slatwall section. Parallel slats are formed between adjacent frontal wall segments and extend between the first side edge portion and the second side edge portion. The adjacent frontal wall segments form a slat opening that extends into a depth of the slatwall section and transitions into a channel generally parallel with a front surface of the frontal wall segments. The slatwall section includes a bottom edge portion forming an angular groove and a top edge portion forming an angular tongue that is mateably engageable with an angular groove of a second slatwall section. A slatwall assembly including a plurality of slatwall sections can be constructed by mateably engaging an angular tongue formed at a top edge portion of a first slatwall section with an angular groove formed at a bottom edge portion of a second slatwall section to form a concealed joint.
