Customer Questions & Answers

How do I accomplish a 1" standoff with this base?

Asked by: jfelton
This base does not provide a 1" standoff. For a 1" standoff, please see the CBS66 (bolted version) or CBSQ66 (screw version); both available with the HDG finish (add HDG to model number). Thank you!

Customer Reviews

6 in. x 6 in. 7-Gauge Hot-Dip Galvanized Column Base is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Excellent heavy-duty product These post bases are made from very heavy gauge steel and hot-dip galvanized. Once anchored in concrete they provide an exceptionally stable base for 6x6 pressure-treated posts (note: so-called 6x6 lumber has a true measurement of 5.5" x 5.5" +/-). These brackets are really massive, over 7 lbs each. They are much sturdier than the typical 12-gauge steel brackets They are anchored about 10" deep into the concrete, then attached to the upright post using two 5/8" x 8" HDG bolts. Once properly anchored, that post is not going anywhere! I would definitely recommend this product to a friend.
