49 (800) 521-9790 alpineitw.com ENGINEERED WOOD PRODUCT SIZES Toe Nailed I-Joist Do not toe nail wood I-joist to headers prior to installing hangers of any type. Toe nailing results in improper hanger installation resulting in gaps and a loose connection, and is a major cause of squeaks. Hanger Over-Spread on Glu-lam Header Top flanges spread wider than the wood I-joist can raise the wood I-joist above the header. This condition can cause squeaky floors. Hanger Not Plumb A hanger cantilevered out from the header can also cause floor squeaking. Max Allowable Loads (LBS per Linear ft.)

Design: • Apply adjustment factors per NDS. • Loads are for LVL & PSL material Douglas Fir-Larch (G = 0.5) • Spacing along length of beam (Parallel to grain) minimum 6 inches. End distance minimum 4 inches. • Table loads are screw capacity to transfer load between plies. Built-up LVL/PSL capacity may be less. Check with manufacturers. • Provide adequate Lateral Bracing against tension due to side framing into main beam. 1¹⁄₂" Min 1¹⁄₂" Min 2" Min 1³⁄₄" 1³⁄₄" 1³⁄₄" 1³⁄₄" 1³⁄₄" ³⁄₄" 2" Min 3¹⁄₂ 3¹⁄₂" 1¹⁄₂" Min 1³⁄₄" 1³⁄₄" 1³⁄₄" 1³⁄₄" ³⁄₄" 2" Min SUPERSPEED ® DRIVE SCREW INSTALLATION FOR LVL W = 11 3 ⁄16" W = 2 3 ⁄4" W = 3 9 ⁄16" W = 5 3 ⁄8" W = 7 1 ⁄8" 1 3 ⁄4 x 7 21 1 ⁄16 x 9 1 ⁄2 3 1 ⁄2 x 3 1 ⁄2 5 1 ⁄4 x 5 1 ⁄4 7 x 7 1 3 ⁄4 x 9 1 ⁄4 21 1 ⁄16 x 11 7 ⁄8 3 1 ⁄2 x 5 1 ⁄4 5 1 ⁄4 x 7 7 x 9 1 ⁄4 1 3 ⁄4 x 9 1 ⁄2 21 1 ⁄16 x 14 3 1 ⁄2 x 7 5 1 ⁄4 x 9 1 ⁄4 7 x 11 1 ⁄4 1 3 ⁄4 x 11 1 ⁄4 3 1 ⁄2 x 9 1 ⁄2 5 1 ⁄4 x 11 1 ⁄4 7 x 14 1 3 ⁄4 x 11 7 ⁄8 3 1 ⁄2 x 11 1 ⁄4 5 1 ⁄4 x 11 7 ⁄8 7 x 16 1 3 ⁄4 x 12 3 1 ⁄2 x 11 7 ⁄8 5 1 ⁄4 x 12 7 x 18 1 3 ⁄4 x 14 3 1 ⁄2 x 12 5 1 ⁄4 x 14 1 3 ⁄4 x 16 3 1 ⁄2 x 14 5 1 ⁄4 x 16 1 3 ⁄4 x 18 3 1 ⁄2 x 16 5 1 ⁄4 x 18 3 1 ⁄2 x 18 LVL and PSL Laminated veneer lumber (LVL) is engineered with sheets of thin veneer structurally bonded together to make headers and beams which span much longer distances and support heavier loads than ordinary lumber. LVL headers and beams are available in the following sizes: Parallel strand lumber (PSL) is made from long, thin strands of wood structurally bonded together in a process to make large cross section beams and columns. PSL headers and beams are available in the following sizes: PSL columns and posts are available in the following sizes: SDSZ\vX4 1 ⁄2 SDSZ\vX3 SDSZ\vX6 KC 3 INSTALLATION ERRORS FOR TOP MOUNT HANGERS KC 4¹⁄₂ KC 4¹⁄₂
