Use a post that looks like it was designed for the job. The square post looks better than a round post and usually does not cost any more. In some cases it is less expensive. We have found that once a contractor uses the PETCO square post, he sees the advantages and keeps on using them. Our square steel post is dip-painted inside and out and has rounded corners for added safety.
