The ABA is designed to attach wooden posts to existing concrete. The built-in 1″ standoff of this adjustable post base helps to prevent rot at the end of the post. The ABA has a slotted anchor hole in the base for adjustability and attaches to the post with nails or Strong-DriveSD Connector screws. This versatile post base makes a cost-effective option for securing a post to the foundation.

This post base is available in model sizes for double 2x, 4×4, 4×6 and 6×6 lumber, both nominal and rough. The new double 2x size can be used for installing a structural post consisting of two 2×4 studs nailed together as well as for securing double 2x beams to a footing for ground-level decks.

Key Features

• The slot in the base enables flexibility around the anchor bolt, making precise post placement easier

Installation

• Use all specified fasteners; see General Notes.
• See ourAnchoring, Fastening and Restoration Systems for Concrete and Masonrycatalog for retrofit anchor options, such asTiten HD,Stainless-Steel Titen HDorSET-3G.
• 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 carports).
• Place the base, cut washer(s) and nut(s) on the anchor bolt(s). Make any necessary adjustments to post placement and tighten the nut securely on the anchor bolt.
• Place the post in the ABA and fasten using nails or Strong-Drive SD Connector screws.
