Questions & Answers


can this be installed in pre existing concrete, drilled and hammered into place?

Asked by Eric September 27, 2020

Here is a link to install instructions:

what is the maximum vertical load this will carry on a 4X4 post holding a 300 gal water tank?

Asked by puna September 8, 2020

The allowable loads for the EPB44 vary depending on seismic design category and condition; please see the following link to the load table for complete details: It would be up to the Designer/Engineer of Record to determine if it is suitable for the specific application. Thank you!

What size galvanized nails does it take?

Asked by tom June 29, 2020

The EPB44 requires 0.162" x 3 1/2" common nails. Thank you!

Ive installed the anchor to the concrete, and now that the concrete is dry the anchor seems to move a little. Is there a way to fix this?

Asked by Gabriel June 16, 2020

Please contact our Engineering Support Department during normal business hours to discuss the installation - 800/999-5099. Thank you!

Would you recommend these to use in footings for a tree house?

I only used this item for a birdhouse support beam.

Asked by matt May 7, 2020

Do yourself a big favor and just replace the footing. Having installed fence fro years I've always regretted trying to salvage posts and footings. Do it right once or do it wrong over and over again.

how are you supposed to install 3.5 inch nails into a 6*6 post?

Asked by Matt March 30, 2020

I am guessing that you are concerned with the nails installing from opposite sides. The part has been tested with the specified fasteners and they will slide past each other. Thank you!

Install with 6- 16D nails. Then what is the point of the 2 larger holes?

Asked by Matt March 22, 2020

Simpson stated in an earlier question that the large holes are used to hold the bracket during the manufacturing stage. They are not for anchors. I'd like to caution you on the 6-16d nails--a cluster of nails like that in one small area, especially that close to the bottom of the post, can cause sever splitting. I pre-drilled pilot holes in my posts, and used the #9x2 1/2" bonderized galvanized screws, also available at Home Depot. If you use the nails, get the bonderized galvanized nails from Home Depot--smooth 16d nails will rust out in a couple years.

Can it be used for pressure treated wood

Asked by Jace March 18, 2019

I installed it with pressure treated wood post and it is stable. I did anchor it with cement over a year ago.

A must for my DIY project. Standing in confusion as to what I should use for stabilizing my post and beams. The best use and functional placement was the elevated post base. I did not want my post buried into the ground and the simple installment for my self poured and mixed concrete. This was a better choice for cost and effectiveness.
