Used three brackets to support a 48 x 5 shelf holding glassware behind my home bar. Secured the brackets using 3 of the supplied screws for each bracket into studs. The brackets with only about 10 lbs of weight the shelf deflects downward, risking dumping its contents. Might be suitable as corner bracing.
