LRU Rafter Hanger


The LRU offers an economic alternative for those applications requiring a sloped hanger for rafter-to-ridge connections. Used with solid-sawn rafters, the LRU'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 LRU offers comparable or better load capacity to other rafter hangers at a reduced cost while using fewer fasteners.

Features:

Material: 18 gauge

Finish: Galvanized (G90); see Corrosion Information.

These models are approved for installation with the Strong-Drive SD Structural-Connector screw.
Table
  1. 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.
  2. Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  3. Allowable loads in the table are based on a maximum joist slope of 45° (12:12). For slopes greater than 45°, up to 49° (14:12), the allowable loads are 0.85 of the table loads.
  4. 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.
  5. 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.

Alternate Installation for Retrofit

Table
  1. Allowable loads are based on a minimum 3" thick carrying member.
  2. Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  3. Fasteners may be angled upward a maximum of 45 degrees.
  4. SCREWS: Simpson Strong-Tie SD #10x2 1/2 (model SD10212) = 0.161" dia. x 2 1/2" long.

Alternate Installation for Retrofit Applications

When an existing roof deck prevents the horizontal installation of fasteners, Strong-DriveŽ SD #10x2 1/2" screws may be installed sloped upward to match the roof pitch (45° max.). Use table values for an installation with 10d nails when SD screws are sloped. Nails may not be installed sloped upward.


top Minimum Ridge Beam Depth (in inches)

Table
  1. Minimum ridge beam depths shown assume rafter and ridge beam are flush at the top.
  2. 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.
  3. 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.
