A wall system includes a grid constructed of horizontal main support channels mounted on a fixed wall and a plurality of spaced vertical standards secured to the channels at the front thereof. Each channel has a U-shaped cross-section with rearwardly extending arms diverging slightly so that overlapping channels may nest, one in the other. Ears projecting outward from the ends of the arms and lie in a common plane are used for securing the channel in place. The web of each channel is provided with a longitudinally extending row of equally spaced apertures. Each standard is provided with two longitudinally extending rows of holes with the rows being spaced by the distance between apertures and the holes in opposite rows being connected by lines that are perpendicular to the longitudinal axis of the standard. Fasteners extending through holes in each row are received by adjacent apertures in the channel web to automatically secure the standard in a position at right angles to the support channel.
