dimensions of cb66 ?

Asked by: Anonymous
Inside square plate matches treated 6x6 post, so 5 1/2" X 5 1/2". A rough guess, they are 18"-20" long (total). Set nice and deep in the concrete. Solid mounting.

Hot Dipped?

Is this product Hot Dipped or Electroplated?
Asked by: Homebuilder
The CB66 is made from G90 galvanized steel which is galvanized by a hot-dip process (prior to the part being fabricated), however, this base is also offered in a post-fabricated hot-dipped version (CB66HDG). The CB66 (G90) has a low level of corrosion protection while the CB66HDG has a medium level of corrosion protection. Please see the Corrosion section of our website to determine the recommended finish for your specific application based on environment, type of treated wood being used, chemical retention, etc. Thank you!

Customer Reviews

CB 6 in. x 6 in. Galvanized Column Base is rated 4.3 out of 5 by 13.
Rated 5 out of 5 by from 5 Star Review Rating provided by a verified purchaser

Rated 5 out of 5 by from Simpson Strong-Tie 6x6 Column Base Used these to fasten polebarn posts to 10" concrete filled tubes. They are much more solid and sturdy than online research lead me to initially believe. These allow poles to be installed slightly above grade, reducing the potential for water damage to treated poles and the brackets themselves. Setting them in wet concrete is a breeze. Makes squaring the building simple too. Beats anything I have used in the past. Almost 1/4" thick steel, VERY sturdy.

Rated 5 out of 5 by from Best Base These bases are strong and easy to install. I will never have to replace the posts again. Could not get them in the store had to order on line. Well worth it.

Rated 4 out of 5 by from Beefy Hardware This is just what I was looking for. I'm building a raised porch with roof, so concerned with high wind uplift. This should do the trick and is very solid.

Rated 5 out of 5 by from Great product. Extremely strong. Used for a large deck some of the 6x6 posts were a little tight but nothing a rubber mallet couldn't solve. Recommend completely

Rated 4 out of 5 by from CB 66 This bracket was a little heavier than needed but did thejobjust fine
Date published: 2016-08-23
Rated 2 out of 5 by from Not Quit Right The product is supposed to fit 6" x 6" porch posts. But the base measures 5 3/8" and most 6" x 6" post measure at least 5 1/2" but can be up to 5 5/8". So, required a lot of post shaving to get posts to fit in bracket. More labor intensive than expected. Had to use this bracket as it was specified on plans.
