The Simpson Strong-Tie RPBZ Retrofit Post Base is designed to reinforce existing posts and columns. The single, versatile model will fit on any size post consisting of a double 2x4 or larger. RPBZ can also be used to reinforce new post-base connections, such as braced carports, patio covers, decks and other structures. The Simpson RPBZ can be installed with the CPS composite plastic standoff to meet a 1" post standoff code requirement. A single RPBZ can be installed on a post that is flush to a corner, and two RPBZs can be installed at away from edge conditions to fortify the post base connection to resist both wind and seismic forces. . The Strong-Tie RPBZ post base features a G185 ZMAX galvanized finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.

• Use all specified fasteners.
• Simpson Strong-Tie 1/4" x 1 1/2" Strong-Drive SDS Heavy- Duty Connector and base connection fasteners are not provided with RPBZ. Simpson Strong-Tie CPS series Composite Post Stand-Off sold separately.
• Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non top-supported installations, such as fences or unbraced car ports.

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values.
