Made from 3/16-inch hot rolled steel, this L bracket carries surprising strength. Two holes spaced equally for mortar lagging are provided to secure the mounting bracket to the wall. The 3/16-inch hole accommodates a Teks screw for fastening the awning frame. The second hole accommodates a 3/8-inch lag screw. The large #10 mounting bracket works with 1-inch or 3/4-inch square tubing. Use the fitting for wall-mounted retractable or stationary awnings.
