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-Drive® SD Connector screws. This versatile post base makes a cost-effective option for securing a post to the foundation.
The slot in the base enables flexibility around the anchor bolt, making precise post placement easier
1" stand-off design meets code requirements for structural posts installed in basements or exposed to weather or water splash
Increased uplift loads for earthquake or wind loading
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.
Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
Downloads may not be increased for short-term loading.
Specifier is to design concrete and anchorage for uplift capacity.
For higher downloads, pack grout solid under 1" standoff plate before installation. Base download on column or concrete, according to the code.
Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. For SCL columns, the fasteners for these products should always be installed in the wide face.
Downloads shall be reduced where limited by capacity of the post.
