The RPBZ (Retrofit Post Base) is a high-strength, heavy-duty connector designed by Simpson Strong-Tie for reinforcing existing wood posts on concrete surfaces. It is part of their specialized "ZMAX" line, which is engineered for high-corrosion resistance in outdoor or pressure-treated wood environments. Product Description The RPBZ is a versatile, two-piece-capable bracket used to secure posts that weren't originally anchored when the concrete was poured. Materials: 12-gauge steel with a ZMAX® (G185) Galvanized finish. Dimensions: Approximately 5" tall and 4" wide. Fitment: Extremely versatile; it fits any post size from a double 2x4 up to 6x6 and larger. Installation: Requires a concrete anchor (like a 1/2" Titen HD) for the base and Strong-Drive® SDS Heavy-Duty Connector screws for the post-to-flange connection. Key Benefit: It can be paired with a CPS composite standoff to meet the 1" standoff code requirement, which prevents the post from sitting in water and rotting.
