        A:  Hi Doobs, this is Colin from Simpson Strong-Tie. The PBS is a cast-in-place base for a vertical post. It can be used in deck construction, however you should consult with a qualified design professional familiar with all applicable building codes to determine if it would be suitable for your specific application.

          Best for patio covers
          I use these often for custom wooden patio covers. You can start work soon after they are set; with the drill-in or anchor bolt style, I found that if you start to torque them down too early the concrete can break. The "negative" with these is that you must do your layout perfectly and ensure they are exactly where you want them while the concrete is still wet.

            Good overall, could be longer
            Used a bunch of these during a small pergola construction. I agree with others that they could be longer to engage the cement deeper, but that problem is solved with adding a post anchor to the bottom of it. See photo

              Very heavy duty
              I purchased 7 for a fence and they were much heavier than I expected. The concrete guys had no issues installing. I believe they should work perfectly.

                This anchor isn’t quite as robust as the CBS44; however, is more than adequate for decks outside of hurricane zones. Also, be sure to set the standoff base fully down as there are little indentations to hold it in place on the bracket. I chose to trowel a little bit of concrete underneath the standoff base to help fill the displaced concrete from setting the anchor in the sonotube. I was pleased with the results of this anchor. I prefer the “wet set” style anchors for their superior holding strength. I used the CBS66 on a job and I wrongfully assumed I would be able to plumb a 12’ 6x6 after nailing it to the post base. It was so secure after nailing I couldn’t plumb the post, so, I removed the nails, plumbed and braced the post, then re-nailed the post. Some reccomendations to a person using these for the first time for a drop or flush beam connection: - Set the level of the anchor between 1/4 to a 1/2” low of your target elevation (finish deck height minus deck board and framing thickness). Treated lumber can vary a lot in its width dimensions, so avoid the aggravation of being too high by intentionally being a hair low. You can always use structural composite shims to level the beam. - plumb the beam before nailing off. It’s temping to nail off the beam and “rock and roll” however, take the time to plumb the beam or risk your joist cuts having to be cut fractions of a degree off to fit properly. Ask me how I know. - I would not recommend these bases incorporated with a monolithic slab. If anything, pour your column footings before your slab if you want to use these. If you do use them with a monolithic pour, have someone dedicated to focusing on the post bases alone; or, have some jig made up to preset the post bases before you pour. They take time to align so dont think you can pour a slab and them set these in quickly. For large light pole bases we would hand tighten the steel bases to a slab of plywood and use that as the jig to set the light pole anchors. That could work for these too i suppose.

                Must for my deck!
                I was looking for a product that would provide strong lateral support for 4x4 posts (approx 8' tall) that would be supporting fence panels on a deck. After searching online and at various hardware stores, these appeared to seat in the concrete the deepest and also have the highest bracing for the posts. See my attached pic for the final product. I was very pleased!
