Retrofit Post Base

RPB-TZ

Reference Series: RPBZ
RPB-TZ post base attaches 4x4 or larger wood posts to concrete or wood surfaces after the post is in place. Can be installed with 1 or 2 RPB-TZs (single or double). Post may also be installed on our CPB composite post base product which provides a 1" stand-off as required in untreated wood installations. Installs with concrete screws, so no more mis-installed, mis-located anchor bolts!
