These U-shaped hangers encapsulate the top flange of the joist, so no web stiffeners are required for standard installation. The SUR and SUL hangers are identical except that they are skewed 45° to the right (SUR) and the left (SUL), respectively. SUR ZMAX® Galvanized Joist Hanger for 2×10, Skewed Right (Pack of 1680).
