Questions & Answers


Can I use this to protect play fort posts That were standing in dirt? How much weight do they hold?

Asked by Mom September 23, 2020

With the post in the vertical position and a total height of 8' it is estimated to be around 6500 lbs. So the design of this base support exceeds this limitation plus the weight of the post.

Can these be used with an existing deck where the posts were installed directly onto the concrete?

Asked by Phil September 4, 2020

Yes, but you will probably have to adjust the height of each post to accommodate the bracket. This would require that you jack up the deck immediately adjacent to the post to make the proper adjustment.

can i use this anchor to put on top of porch to do a pergola on top

Asked by mv July 8, 2020

Anchors post to the floor (slab in my case) of my deck

My post are rough cedar and are a true 4x6, can it adjust to fit?

Asked by Cp123 June 3, 2020


Can I use this to secure a pergola post?

Asked by Jaime April 1, 2019

I don't see why not. That assumes at least four posts will be used. If you are thinking of one of those unbrella type pergolas with one or two posts, they won't.

what is the appropriate/correct anchor bolt to use with this?

Asked by bub October 22, 2018

I used 5/8” x 10” wedge anchor. 1/2” would also work. You can prob use wedge, sleeve or epoxy to anchor depending upon what you prefer.

Can these be used in wet concrete? I would set the 5/8" bolt in wet concrete then place standoff...

Asked by SH July 24, 2018

You could but shouldn't. The standoff helps to prevent water wicking up the post and rotting it from the bottom up.

How high off the concrete will this raise the 4" x 6 " post?

Asked by paul June 2, 2018

Less than an inch. 3/4 as far as I recall.

I don't understand what makes these adjustable?can they be adjusted up and down? if so how?

Asked by johnw May 14, 2018

No they're adjustable side to side so you have some room to align a few posts.

can this be used for a base for a gate?

Asked by HomeDepotCustomer May 22, 2017

No. These are meant to take direct load to concrete so think of a post on a deck pier with the post being cross tied. They're not designed to take lateral stress.

I wish you carried the much stronger 4x6 post base. The ABU46Z Simpson strong tie. Much more lateral and vertical support. Also look better

Sinking the bolts to the proper depth takes some skill. Bracket may bow if concrete sagged during bolt installation. Side to side adjustment makes it easy to line up for beam installation.
