I'm about to repair a wood fence on the side of my yard. It's rotted
over the years, especially the posts and bottom rail which are sitting
directly on top of the concrete pad. I'm going to replace the posts,
rails and fencing. The existing posts were attached to the concrete
pad using L-brackets and have lasted 20+ years. For the new posts, I
was going to attach them to the concrete using a post base and
anchor... the kind Simpson StrongTie make (perhaps model ABA44Z).
However, the sign at the Home Depot said "not recommended for non
top-supported installations (like fencing)".
So, I'm a bit confused. How can that not be strong enough, yet some
lousy L-brackets have held the existing posts for 20+ years? Does
anyone have experience of this or a practical suggestion?
FYI, the posts would be 6' 4x4's, 6' apart, using 2 2x4's for rails.
The fencing is 6' 1x6's. I was going to then use screw decks to screw
the fencing to the rails. All of the wood is cedar.
Thanks in advance for the help, folks.
