Joist hangers are designed to provide support underneath the joist, rafter or beam to provide a strong a connection. Simpson Strong-Tie offers a diverse line of hangers to handle almost any application with top flange, concealed flange and field-skewable and slopeable options. The LUS is an easy-to-install, economical hanger designed for common lumber sizes. This widely used hanger features double-shear nailing that distributes the load through two points on each joist nail for greater strength. This allows for fewer nails, faster installation and the use of all common nails for the same connection.
