48 (800) 521-9790 ORDERING INFORMATION FOR WOOD I-JOIST CONNECTORS COMMON INSTALLATION ERRORS WITH USE OF A NAILER Ordering information… • Select style or type of hanger. (Example: RA style or RS type) • Specify series or width. (Example: 35 Series = 2 3 ⁄8") • Specify height in inches. (Example: 18 = 18") Specify… RA – hanger style or type load. RA35 – – hanger series (width). RA – – 18 hanger height (inches). RA3518 Single: 2 Series (2x) .............. W = 1 9 ⁄16" 25 Series .................. W = 11 3 ⁄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-2 (2x) .......... W = 3 1 ⁄8" 25 Series-2 ............... W = 3 9 ⁄16" 2.06 Series ............... W = 4 1 ⁄8" 35 Series-2 ............... W = 41 3 ⁄16" 3 Series-2 (3x) .......... W = 5 1 ⁄8" 4 Series-2 (4x) .......... W = 7 1 ⁄8" Wood I-Joist Sizes A. Refer to the wood I-joist manufacturer's product catalog for the wood I-joist series given in the table for wood I-joist sizes. B. Determine that the top plate will take the required nails as shown in the catalog tables. Contact the wood I-joist or engineering wood beam producer for nailing limitations when laminated engineered lumber is used as top plates and nails penetrate parallel to the glue line. C. With the many types of wood I-joists available, the design loads given are hanger design loads attached to Douglas fir, larch or southern pine top plates and do not reflect the design load of the wood I-joist. Loads must be reduced where wood shear capacity or seat-bearing and joist nailing result in lower values. Contact your wood I-joist manufacturer's representative for wood I-joist allowable loads. D. For proper web stiffener requirements (web stiffeners and backing blocks may not always be required) recommended nailing and nail limitations, refer to the wood I-joist manufacturer's installation instructions. Follow all requirements for blocking, wood stiffeners, fillers and temporary bracing. E. Do not allow workers on the framing system until all hangers, blocking and bracing have been nailed and installed. What are Nailers and Ledgers? A wood nailer is a plate which attaches to the wall support. A nailer may be used in conjunction with a steel I-beam, concrete block wall, stem wall or other support. The beams, joist and sheathing then attach to the nailer. When choosing a nailer, consider installation requirements, job needs and available resources. A ledger is similar to a nailer, however, the wide dimension of a ledger is vertical rather than horizontal, as with the nailer. Nailer too Thin… If the selected nailer is too thin, the following may occur: 1. The nails will not penetrate fully. 2. Room will not allow use of all face nails required for certain hangers. 3. Splits in the nailer will result from nails penetrating through the I-beam. Note: Substitution of shorter nails reduces the allowable load values. Nailer too Narrow… If the selected nailer is too narrow, the following will be necessary: 1. The hanger must be cantilevered out for clearance or 2. The hanger must be tilted back for top flange support. Note: Nailer should not be more than 1/4" narrower or load values will be greatly reduced. Nailer too Wide… Cross-grain bending may result if the nailer is wider than the I-beam. Note: An overhang of more than 1/4" is not recommended. DESIGNER AND INSTALLER INSTRUCTIONS * Warning: Do not allow the joist hanger to contact the steel I-beam or the concrete wall. This may cause squeaking noises.
