Additional Corrosion Protection

These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

These models are approved for installation with the Strong-Drive SD Structural-Connector screw.
See the load values below.
Table
  1. Uplift loads have been increased for wind or earthquake with no further increase allowed; reduce where other loads govern.
  2. Downloads may not be increased for short-term loading.
  3. Specifier to design concrete for uplift capacity.
  4. ABU products may be installed with either bolts or nails (not both) to achieve table loads. ABU88 and ABU88R may be installed with 8-SDS 1/4"x3" wood screws (sold separately) for the same table load.
  5. For AB bases, higher download can be achieved by solidly packing grout under 1" standoff plate before installation. Base download on column, grout, or concrete according to the code.
  6. HB dimension is the distance from the bottom of the post up to the first bolt hole.
  7. 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.
  8. Downloads shall be reduced where limited by the capacity of the post. See Post Capacities for common post allowable loads.
  9. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long. See other nail sizes and information.
