The TSF is a fast and accurate method for spacing trusses that eliminates layout marking of top plates and can be left in place under the sheathing. Accuracy is improved, spacing errors are minimized, and it is easy to use. MATERIAL: 24 gauge. FINISH: Galvanized. INSTALLATION: See Installation Sequence below. TSF Truss Spacers do not provide bracing of any kind and are not structural members. The TSF is for spacing only. Refer to instructions from architect, engineer, truss manufacturer or other for bracing and installation information. CODES: See page 12 for Code Listing Key Chart. Model No. Dimensions W O.C. Spacing Total Length TSF2-16 1 16 8' TSF2-24 1 24 10' Code Ref. 180 STEP 1 Nail starting notch to first member. STEP 2 As each successive member is positioned, unfold TSF to next notch. The notch teeth grip member and align it for nailing. STEP 3 If spacer does not align with end truss, break spacer off at notch. Then, hammer spacer flat, fold it under and nail. TSF 141 Plated Truss Connectors TSF Truss Spacer TBD20 Diagonal Truss Bracer The TBD20 is a temporary truss bracing strap system used in conjunction with TSB2 to meet or exceed TPI/WTCA BCSI 1-03 recommendations. When installed on the top and bottom, TBD20 captures the top and bottom truss chords lateral construction and wind forces delivered by TSB2 and transfers it diagonally in tension to the edge of the braced truss system. FEATURES: Higher capacity for wind applications than traditional wood lateral systems. Strap clip system introduces innovative single and double shear combination to achieve higher capacity. Has a low profile that can be sheathed over, eliminating the need to remove bracing prior to sheathing. TBD20 and TSB2, sheathed over, can be a supplemental permanent bracing system to the roof sheathing. MATERIAL: 20 gauge. FINISH: Galvanized INSTALLATION: Use all specified fasteners; see General Notes. TBD20 straps span diagonally at approximately 45 between parallel TSB-2 bracers. Strap shall not be slack, but tight and ready to engage in tension. TBD20 tension straps shall be installed for each direction, thus creating an X-bracing system. To resist construction forces, refer to TPI/WTCA BCSI-03 for location and frequency of X-braced sections. To resist wind forces, the designer of record shall evaluate the structure to determine the location and frequency of X-braced sections. For wind applications, solid blocking between X-braced trusses with LTP5 or RBC to top plate and H2.5 or H2.5A at each strap clip end from truss to top plate are recommended to resist lateral and uplift forces respectively. Design of lateral and vertical load path to deliver forces to ground is by designer of record. CODES: See page 12 for Code Listing Key Chart. Each carton contains 12 straps (each 13 l long) and 24 clips. Typical TBD20 Top Chord Installation 1. Allowable loads have been increased for construction and wind loading with no further increase allowed. 2. 4-10dx1 nails at exterior clip section and 2-10dx1 at interior clip section. 3. Allowable tension loads are based on a 2.5 reduction factor. 4. NAILS: 10dx1 0.148" dia. x 1 long. See page 16-17 for other nail sizes and information. 650 170 TBD20 6-10dx1 1-10dx1 755 Allow.
