Models are available for attaching to existing hardened concrete, wet concrete, as well as wood. The AB series also offers adjustability around the anchor bolt to achieve optimum post placement. Many models provide a 1 in. standoff from the concrete to help avoid post-end rot from moisture.

Questions & Answers

Asked by Josh July 8, 2020

The ABU46Z is not rated for lateral/horizontal loads. It is only rated for vertical (uplift and download). Thank you!

Which would be more stable, this base or Model #CB46 ? Application is for a Japanese Torii inspir...

Asked by monk July 1, 2020

We cannot recommend either base mentioned for a free standing installation. Except for the MPBZ moment post base, post bases do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations (such as fences or unbraced carports). The top of the post must be restrained from moving horizontally by some other means, e.g., by tying the roof into a supporting structure or by adding knee bracing between the posts and beams. Alternatively, see the MPBZ for a post base that provides moment resistance for columns or posts. Thank you!

Can I use the Simpson #10 x 1-1/2 inch Strong Drive SD screws to fasten the post to the stand off...

Asked by Worker November 24, 2018

yes you can.

Is an anchor bolt included? If not, what size and length should be used?

Asked by Hastabeshasta June 17, 2018

No anchor bolt not included, use a 5/8" by 7" or 8" long expansion bolt.

I understand that 16d nails may be used to attach the plate to the post, but it shows a bolt option as well but there is no mention of the bolt size.

Asked by 14StreetGlide April 23, 2018

5/8" by 6" or 7" galvanize bolt with nut and 2 washers. you will have to cut the excess of the bolt off when done.

Was used on an 8" pier with and a 12" footing for a shed. Beams were laid directly in the post base due to a slope needing to keep it close to the ground. Worked fine for our uses. Installed a bolt into the concrete during pouring. I suggest you leave a little over 1" sticking out to accommodate the post base.
