MEMORANDUM OPINION
PER CURIAM.
In this breach of contract case, founded upon diversity of citizenship jurisdiction, 28 U.S.C. § 1332, plaintiffs, Tekonsha Engineering Co., Inc., and Theodore Bargman Co., appeal the district court’s grant of summary judgment to defendant, C.W. Industries, Inc.
Having had the benefit of oral argument and having carefully considered the record on appeal, the briefs of the parties, and the applicable law, we are not persuaded that the district court erred in granting summary judgment to defendant.
Because the reasoning which supports judgment for defendant has been articulated by the district court, the issuance of a detailed written opinion by this court would be duplicative and serve no useful purpose. Accordingly, the judgment of the district court is affirmed upon the reasoning employed by that court in its well-reasoned opinion dated January 26, 2004.
