Handcrafted rolled metal strips provide maximum strength on the Cascade mantel bracket. Produced from heavy-duty 1/4" steel, the Cascade mantle bracket is powdercoated flat black for a contemporary finish. The 6" x 5.5" top plate supports even the heaviest mantel beam. A 500 pound carry capacity is provided with no more than a 30" span. Install into rock or stud wall for a secure structure to last the lifetime of your fireplace.
