Abstract: A system (200) for securing and positioning structural members (20, 30) to supporting walls (10) of a building includes at least one mounting member (205) secured to a surface portion of a supporting structure (10). The mounting member (205) has a plurality of structural member receiving spaces 218 formed thereon for receiving the structural member (20, 30) therein. The mounting member (205) includes a longitudinally extended base plate (210) having a plurality of spaced through openings (212, 214, 215, 219, 234) formed therein. The base plate (210) has a plurality of folded portions (222) formed therein. Each folded portion (222) defines a double walled protuberance (220) extending from a surface of the base plate (210). At least a portion of the double walled protuberances (220) are arranged in pairs disposed in opposing spaced parallel relationship to define a corresponding number of the receiving spaces (218) between each respective pair of double walled protuberances (220).
