Slatwall panels measure 48"H x 96"L x 3/4"W with the grooves running in the 8' direction, spaced 3" on-center with Aluminum inserts and edge cuts for stacking. Inserts can double the strength of the groove when screwed through to the stud wall. Panels are covered with a durable laminate finish on high quality MDF (medium density fiberboard), to form a hard, easy to clean, decorative finish. XXPanels have a 2-3 day lead time and will ship crated, via truck. There is a $40. 00 crating fee per skid, which will hold up to 30 panels.
