A slatwall mounting system includes a rail member and a mounting arrangement. The rail member includes longitudinally extending upper and lower edges, a longitudinally extending upper slot portion including a downward extending undercut a longitudinally extending lower slot portion including an upward extending undercut. The mounting arrangement includes a bracket member having a downward oriented hook portion and a mounting aperture, and a cam assembly having a mounting cam assembled with a user graspable cam driver, the cam and cam driver defining an annular groove for securing the cam assembly to the mounting aperture. The mounting cam is rotatable between a slatwall securing position for mounting engagement with the lower slot of the rail member, and a slatwall releasing position, in response to user manipulation of the cam driver.
