168 Straps Ties DSP/SSP/SP/SPH/RSP4 Stud Plate Ties This product is preferable to similar connectors because of a) easier installation, b) higher loads, c) lower installed cost, or a combination of these features. DSP and SSP provide flexibility in the field can be used as a plate to stud connection AND top plate to stud connection. The RSP4 is a reversible stud plate tie with locating tabs, which aid placement on double top plates or a single bottom plate. MATERIAL: DSP/SSP/SPH-18 gauge, all others-20 gauge FINISH: Galvanized. Some products available in Z-MAX; see Corrosion-Resistance, page 6-7. INSTALLATION: Use all specified fasteners; see General Notes. DSP/SSP-sill plate installation-fill all round holes. DSP/SSP-top plate installation-fill all round and triangle holes SP-one of the 10d common stud nails is driven at a 45 angle through the stud into the plate. CODES: See page 12 for Code Listing Key Chart. 1.Allowable loads have been increased 33% and 60% for earthquake or wind loading; no further increase allowed. 2.When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist such forces should be considered. 3.Allowable loads for DSP installed to a rim joist are 660 lbs. (DF/SP), 545 lbs. (SPF/HF). 4. NAILS: 10d 0.148" dia. x 3" long, 10dx1 0.148" dia. x 1 long. See page 16-17 for other nail sizes and information.

SP1, 2, 3 and SP5: drive one stud nail at an angle through the stud into the plate to achieve the table load (see illustration). 2. Allowable loads have been increased for earthquake or wind loading; no further increase allowed. Reduce where other loads govern. 3. RSP4-see Installation details (1) and (2) for reference. 4. RSP4 F2 is 280 lbs (installation 1) and 305 lbs (installation 2). F1 load is 210 lbs for both installations. 5. Maximum load for SPH in Southern Yellow Pine is 1490 lbs. 6. When cross-grain bending or crossgrain tension cannot be avoided, mechanical reinforcement to resist such forces should be considered. 7. For retrofit application see T-STRAP. 8. NAILS: 10d 0.148" dia. x 3" long, 10dx1 0.148" dia. x 1 long, 8dx1 0.131" dia. x 1 long. See page 16-17 for other nail sizes and information.
