Solid Sawn Lumber Connectors Solid Sawn Lumber Connectors LRUZ Rafter Hanger The LRUZ offers an economic alternative for those applications requiring a sloped hanger for rafter-to-ridge connections. Used with solid-sawn rafters, the LRUZ’s unique design enables the hanger to be installed either before or after the rafter is in place. The field-adjustable seat helps improve job efficiency by eliminating mismatched angles in the field and lead times associated with special orders. The LRUZ offers comparable or better load capacity to other rafter hangers at a reduced cost while using fewer fasteners. FEATURES: • The open design and ability to field-adjust the slope makes the LRUZ ideal for both retrofit or new applications • Accommodates roof pitches from 0:12 to 14:12 • Slopes up or down to 45°. For slopes greater than 45° to 49° (14:12), allowable loads are 0.85 of table loads • For added versatility, the fasteners on the face of the hanger are placed high enabling the bottom of the rafter to hang below the ridge beam (see “Max. C1” dimension) • Can be installed using nails or Simpson Strong-Tie ® Strong-Drive ® SD Connector screws MATERIAL: 18 gauge FINISH: ZMAX® coating INSTALLATION: • Use all specified fasteners. See General Notes. • Joist fasteners must be installed at an angle through the rafter or joist into the header to achieve the table loads. • See alternate installation on page 86 for retrofit applications.
