RTA Rigid Tie® Angle


On This Page

The RTA is designed to connect two wood members at a 90° angle. This rigid tie angle fastens the members on two sides, eliminating the need for angle bracing. Manufactured to high-quality standards to ensure solid performance, this rigid tie connector features a galvanized finish for added corrosion resistance.

Key Features

  • Ideal for gates, fences or any project where a 90° connection is needed
  • Fastens with Simpson Strong-Tie® Strong-Drive® SD screws (not included)
  • Provides a strong 90° connection without 45° cuts or angled fastening


  • RTA2Z — 16 gauge; all others — 18 gauge


  • Galvanized or ZMAX® coating; see Corrosion Information


  • Use all specified fasteners; see General Notes
  • Install vertical members first, then attach horizontal members for easier alignment
  • To aid positioning and prevent skewing, seat wood member in bracket with a C-clamp before securing
