Porch Post Base Mounting Blocks are made from 1-1/4" thick AZEK PVC (impervious to moisture) or weather resistant 1-1/2" thick Cypress wood.
Recommended for wood or synthetic porch floors. Not for Newel Posts: Use a Newel Mounting Kit to professionally install Newel Posts.
When installed beneath your Porch Posts, our Blocks extend approximately 1/4" on all sides. Order correct size to fit your Porch Posts. Half Blocks are used when Half Posts are installed against walls. See Installing Base Mounting Blocks.
