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.

1.Factored uplift resistances have been increased 15% for wind or earthquake loading; no further increase is allowed.
Reduce where other load durations govern.
2.Factored resistances shown are applicable for roof slopes up to and including 45° (12:12).
For roof slopes greater than 45° up to and including 49° (14:12) multiply the tabulated resistances by 0.85.
3.LRUZ’s may be installed using Strong-Drive ® SD#10x1½" Connector screws into the header and Strong-Drive SD#10x2½" Connector screws
into the joist at full 16d capacity.
4.For single 2x headers, use 10dx1½" nails into the header and 10d commons into the joist.
Multiply the tablulated 10d capadity x 0.77. Alternately, install Strong-Drive SD Connector screws (see footnote 3 above).
5.For alternate installation under retrofit applications, Strong-Drive SD#10x2½" Connector screws may be installed sloped upwards to match
the roof slope (45° max). Multiply the tabulated 16d values x 0.73. See Alternate Installation for Retrofit Applications detail on page 93.
6.NAILS: 16d = 0.162" dia. x 3½" long, 10d = 0.148" dia. x 3" long; 10dx1½ = 0.148" dia. x 1½" long. See pages 22-23 for other nail sizes and information.
7.SCREWS: SD#10x2½" (SD10212) = 0.161" dia. x 2½" long; SD#10x1½" (SD10112) = 0.161" dia. x 1½" long.

Alternate Installation for Retrofit Applications
When an existing roof deck prevents the horizontal installation of fasteners, Strong-Drive® SD #10x2 1⁄2"
Connector screws may be installed sloped upward to match the roof pitch (45° max.). Use table values
for an installation with 16d nails x 0.73 (see footnote 5) when SD screws are sloped. Nails may not be
installed sloped upward.

HH Header Hangers
For fast, accurate installation of door and window headers and other cross
members. HH header hangers can speed up the job, strengthen the frame, and
eliminate the need for trimmers.
MATERIAL: 16 gauge FINISH: Galvanized
INSTALLATION: • Use all specified fasteners. See General Notes.
• Attachment to 2x studs will result in two round holes not being filled
in the studs and reduction in capacity. See table for capacities and
nailing requirements.
