Systems for mounting racks in dishwashing appliances
A dishwasher appliance includes a tub defining a wash chamber, and a rack assembly. The rack assembly includes a bracket positioned within the wash chamber of the tub. The bracket includes a roller extending therefrom, and a pair of posts mounted to the bracket. The pair of posts extend through an outer surface of the tub, and a brace is positioned opposite the bracket on the outer surface of the tub. The brace includes a snap projection configured to engage the pair of posts such that the snap projection hinders the pair of posts from retracting through the outer surface of the tub. A pair of fasteners extend through the brace into the pair of posts, where the pair of fasteners secure the brace to the pair of posts.
