1. Tabulated loads are the total allowable loads of all carried members combined; the load on any single carried member shall not exceed 25% of the total published load for the THJM2-4 or 20% of the total published load for the THJM2-5. 2. Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern. 3. A minimum 2-ply carrying member is required for the 1⁄4"x3" Strong-Drive ® SDS Heavy-Duty Connector screws (provided). For single 2x carrying members, use 1⁄4"x1 1⁄2" Strong-Drive SDS screws (not supplied) with corresponding loads.

4. A minimum 2-ply carrying member is required for the tabulated loads. 5. Truss chord cross-grain tension may limit allowable loads per ANSI/TPI 1-2007. The optional triangle holes may be used for installation on 2x6 and larger carrying members, for a total of 10 fasteners into the carrying member, to resist cross-grain tension forces when no other mechanical reinforcement is available. 6. Tabs on the seats of the THJM hangers have obround holes for optional 10dx1 1⁄2" slant nails (2 per carried member) when additional uplift capacity is required. Total allowable uplift with the optional 10dx1 1⁄2" slant nailing is 970 lbs. (DF/SP/SPF/HF).
Plated Truss Connectors
The THJM is a non-welded hanger designed to carry radial-end jack framing and provide optimal efficiency for those multi-plane, angled bay roofs over breakfast, study and library alcoves. The unique patent pending design of the THJM accommodates 2x4 girder bottom chords and uses our Strong-Drive® SDS Heavy-Duty Connector screws for easy installation with minimal fasteners. FEATURES: • The THJM hangers are designed for installation with 1⁄4"x3" Strong-Drive® SDS Heavy-Duty Connector screws that are included with the parts. • The THJM2-4-SDS3 is designed for four incoming jack trusses with the outer jacks being 22 1⁄2° from the face of the girder and the inner jacks being 45° from each other and the outer jacks. • The THJM2-5-SDS3 is designed for five jacks coming into the hanger at 30° from the girder and each other. • Tabs on the seats of the THJM assist in the placement of the jacks and also include obround holes for optional slant nails (10dx1 1⁄2") when increased uplift is required. MATERIAL: 12 gauge FINISH: Galvanized INSTALLATION: • Use all specified fasteners. See General Notes. • Each carried jack truss requires one 1⁄4"x3" Strong-Drive SDS Heavy-Duty Connector screw installed into the bottom chord through the bottom of the hanger seat. • For installation on girders with 2x6 or 2x8 bottom chords, install one additional 1⁄4"x3" Strong-Drive SDS Heavy-Duty Connector screw in the triangular hole on each vertical strap. • Install two (2) 10dx1 1⁄2" slant nails in the obround holes on each of the seat tabs to achieve the additional uplift load noted in the footnote. CODES: See page 12 for Code Reference Key Chart.
DSC Drag Strut Connector The DSC drag-strut connector transfers the diaphragm shear forces from the girder truss or beam to the shearwalls. The new DSC5 has been designed to optimize fastener location, resulting in a connector that outperforms the DSC4 with fewer fasteners. The DSC2 is a smaller, lighter version that installs with fewer screws. FEATURES • The DSC5 requires 40% fewer fasteners than our previous DSC4, and gets 12% higher loads • Left hand and right hand versions available • DSCs install with the 1⁄4"x3" Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws provided MATERIAL: DSC2—7 gauge, DSC5—3 gauge FINISH: DSC2—Galvanized; DSC5—Simpson Strong-Tie® gray paint INSTALLATION: • Use all specified fasteners; see General Notes. • Strong-Drive SDS Heavy-Duty Connector screws are provided. CODES: See page 12 for Code Reference Key Chart. Model No.
