Product Description
The Simpson APB66R Ornamental Rough 6x6 Post Base is part of the Simpson Strong-Tie Outdoor Accents Mission Collection, engineered to secure a post or column to concrete for outdoor structures such as pergolas, patio covers, and other top-supported builds. Constructed from 12-gauge steel with ZMAX galvanization and a black powder-coat finish, this post base delivers superior corrosion resistance for exterior and treated-wood applications. A built-in 1-inch standoff from the concrete surface helps protect post ends from moisture-related rot, combining structural performance with decorative appeal.

Frequently Asked Questions
- What lumber size does the APB66R fit?
- The APB66R is designed specifically for rough cut 6x6 lumber, meaning the post must have an actual measured dimension of 6 inches by 6 inches. It is not compatible with nominal 6x6 lumber, which typically measures 5-1/2 in. x 5-1/2 in. If you have a nominal post, see the APB66 instead.
- What fasteners are required to install the APB66R?
- Install with (4) STN22 Washers, (4) SDWS22312DBB Screws, and (1) 5/8 in. Concrete Anchors. Fasteners are sold separately.
- Why does the APB66R have a 1-inch standoff?
- The 1 in. standoff keeps the base of the post elevated above the concrete surface, which helps prevent moisture from accumulating at the post end and reduces the risk of rot over time - an important benefit for outdoor applications exposed to the elements.
- Is the APB66R suitable for high-wind or seismic regions?
- Yes. The APB66R is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for use in areas where enhanced structural performance requirements apply.

Note: This connector is designed for rough cut lumber, NOT nominal lumber (most common). This will only fit a post that measures an actual 6 in. x 6 in. If you have a nominal post measuring 5-1/2 in. x 5-1/2 in., you will need the ornamental post base.
