LRUZ Rafter Hanger
On This Page
Product Details
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.
Key Features
- The open design and ability to field-adjust the slope make the LRUZ ideal for both retrofit or new applications.
- Accommodates roof pitches from 0:12 to 14:12.
- Slopes up or down to 45° (12:12). For slopes greater than 45° up 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 in Standard Installation table).
- Can be installed using nails or Simpson Strong-Tie® Strong-Drive® SD Connector screws.
Material
- 18 gauge
Finish
- ZMAX® coating (G-185); see Corrosion Information
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 table for retrofit applications

Minimum Ridge Beam Depth (in inches)
- Minimum ridge beam depths shown assume rafter and ridge beam are flush at the top.
- Minimum ridge beam depths have been determined to ensure the Max. C1 dimension for the LRU is not exceeded. Deeper ridge beams may be required to support the rafter loads as determined by the Designer.
- The International Residential Code requires the ridge to be not less in depth than the cut end of the rafter unless the ridge is designed as a beam.
- Slopes greater than 12:12 are download only.

Load Tables
Standard Installation
These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.
These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.
- Allowable loads are based on a minimum 3" carrying member. For single 2x carrying members, use 10dx1 1/2" nails into the face and 10d commons into the joist, and reduce the allowable load to 0.81 of the tabulated value for 10d nails. Alternatively, use SD #10x1 1/2" into the face and SD #10x2 1/2" into the joist as shown in the table.
- Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
- NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long.
See other nail sizes and information. - SCREWS: SD #10x2 1/2 (model SD10212) = 0.161" dia. x 2 1/2" long, SD #10x1 1/2 (model SD10112) = 0.161" dia. x 1 1/2" long.
Typical LRUZ Installation
Alternate Installation for Retrofit Applications
When an existing roof deck prevents the horizontal installation of fasteners, #10x2 1/2" Strong-Drive® SD Connector screws may be installed sloped upward to match the roof pitch (49° max.). Use table values for an installation with 10d nails when Strong-Drive SD Connector screws are sloped. Nails may not be installed sloped upward.
Alternate Installation for Retrofit
- Allowable loads are based on a minimum 3" thick carrying member.
- Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
- Fasteners may be angled upward a maximum of 49°.
- SCREWS: SD #10x2 1/2 (model SD10212) = 0.161" dia. x 2 1/2" long.
