R RM 3.56/12 4295 lb Down Load Nominal 2x Width Seat Depth 4 1 ⁄2" RA/RAI R RA/RAI RAU RMI RMU ROOF STRUCTURE JOIST AND PURLIN HANGERS Design Features… of the R series offer a wide application flexibility, particularly to the panelized construction and wood I-joist industry, including seven different versions: (1) Standard versions (2) Saddle versions (3) Offset versions (4) Skewed versions (5) Top Flange Down versions (6) Top Flange Open/Closed versions (7) Seat Sloped versions Additional design features provide easier, faster installation, greater load capacities and strength: • Superior flange design • Higher load values • Stirrup design fully maximizes metal surface area where it is vital to construction needs • Uplift nailing on special order WOOD I-JOIST SIZED Single: 2 series (2x) W = 1 9 ⁄16" 25 series W = 1 13 ⁄16" 2.06 series W = 2 1 ⁄16" 35 series W = 2 3 ⁄8" 3 series (3x) W = 2 9 ⁄16" 4 series (4x) W = 3 9 ⁄16" Double: (-2) 2 series (2x) W = 3 1 ⁄8" 25 series W = 3 9 ⁄16" 2.06 series W = 4 1 ⁄8" 35 series W = 4 13 ⁄16" 3 series (3x) W = 5 1 ⁄8" 4 series (4x) W = 7 1 ⁄8" Material… 12 ga., 3 ⁄16" and 1 ⁄4" prime quality steel. R and RA/RAI: 12 ga. and 3 ⁄16" steel. Nails… see table. Loads… tested load values are from independent laboratory tests ® conducted in accordance with code criteria, with a minimum safety factor of three. Finish… SUPERSPEED ® gray paint. Design Dimensions… H is sized for wood I-joist heights. Ordering/Specifying Information: Saddle… add S to stock no. and width of supporting beams. (Example: RI410x S = 5 1 ⁄4) Offset Top Flange… add OS to stock no. and direction of offset left or right. (Example: RI 410x, R = Right, L = Left) Skewed… add SK to stock no. and direction and degree of skew. (Example: RI410X SKL 30°, R = Right, L = Left) Top Flange Down. . add TFD to stock no. and direction and angle. (Example: RI 410X TFDL 15°, R = Right, L = Left) Top Flange Open… add TF to stock no. and degree. (Example: RI410x TFO 20°, O = Open, C = Closed) Seat Sloped… add SL to stock no. and direction of slope (up or down). (Example: RI410x SLD15°, D = Down, U = Up) Any of the above are available in a combination hanger. (Example: RI410 Offset right, skewed 45° left, sloped down 20° pitch) RI410x OSR/SKL 45°/SLD 20° Skewed and Sloped Hangers… (see page 38) are available, specify angle and whether left or right, up or down. Due to the infinite variety of custom orders, sloped hangers are not code evaluated. Design loads of the nearest equivalent hanger should be used as a general guide, subject to specific engineering designs. Note… web stiffeners and backing blocks may not always be required. Consult the engineered wood I-joist manufacturer for web stiffener and backing block requirements, and recommended nailing schedule for each. Laminated ledgers must be properly evaluated by the designer. A solid wall backing and ledgers at least 3x must be used to attain load values. Hangers used to support multi-ply joist; the joist must be fastened together to act as a single member before installation into the hanger. Code Report Reference(s)… ESR-2930
