178 Miscellaneous RTC/FWH/FWL Rigid Tie Connectors RTCH U.S. Patent 6,022,165 RTR The RTC series secures two wood members forming a 90 corner to a vertical post. The RTC42 and RTC44 are heavy-duty structural connectors. Based on loads of 40 lbs per sq ft, a 10 x 10 deck can be built using 2x8 joists and 4 RTC42s. See the table for Post and Joist sizes. The RTCH is hidden inside the connection, and secures three 2x members at 90 angles. RTB-a bracket for intersecting 2x members. FWH and FWL-4 way connectors for 2x members with bendable flanges. RTA-connects two 2x wood members at a 90 angle. RTF-connects two members in a pass-through application. RTR and RTU-a 2x member crosses another. MATERIAL: RTC44-14 gauge; RTA2-16 gauge; RTCH, RTR, FWL and RTB -20 gauge; all others-18 gauge FINISH: Galvanized. Some products available in stainless steel or Z-MAX; see Corrosion-Resistance, page 6-7. INSTALLATION: Use all specified fasteners. See General Notes. Install vertical members first, then attach horizontal members for easier alignment. Seat wood member in bracket with a C-clamp before securing to aid positioning and prevent skewing. Always follow manufacturers instructions when using power tools and building equipment. CODES: See page 12 for Code Listing Key Chart.
