RST Hurricane Tie

RST

The RST is a versatile connector that provides uplift resistance for roof trusses and rafters for applications where attachment to the wall stud rather than the top plate is preferred. The unique geometry allows the connector to straddle a double 2x top plate either with or without a 5/8" bearing strip. The strap portion of the connector can be bent about the perforated strap portion of the connector to enable connection to either the narrow or wide face of the stud.

Material

  • 18 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners; see General Notes.
  • For connections to the wide face of the stud, bend the RST about the perforated strap portion of the connector. Bend only once.

Codes

  • Testing performed in accordance with ICC-ES AC-13. Contact Simpson Strong-Tie for the latest load values and testing information.

  1. Loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Allowable loads are for one connector. A minimum rafter thickness of 2 1/2" must be used when connectors are used on each side of the rafter and on the same side of the plate (exception: connectors installed such that fasteners on opposite side do not interfere).
  3. Loads apply to DF, SP, HF and SPF lumber species.
  4. Allowable F1 load for the RST-3 installed into the narrow face of stud with no bearing strip is 60 lbs.
  5. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or cross-grain bending of the truss or rafter members.
  6. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces may be required.
  7. Connectors are shown on the inside of the wall for clarity. Installation on the outside of the wall is acceptable, provided a minimum 3 1/2" overhang. For a Continuous Uplift Load Path, connections in the same area (i.e. truss to plate connector and plate to stud connector) must be on the same side of the wall.
  8. Nails: 8d x 1 1/2= 0.131" dia. x 1 1/2" long. 10d x 1 1/2= 0.148" dia. x 1 1/2" long.
  9. Screws: Strong-Drive® SD #9 x 1 1/2" (model SD9112) = 0.131" dia. x 1 1/2" long
