Our horizontal rails feature 2″ ends to fit securely into 2″ bored out holes in each fence post. This Doweled installation is much stronger than the conventional Nail On method, because of the weight of the fence sections rests on 2″ dowels rather than on a few nails or screws.
We also use 5×5 posts rather than the standard 4×4’s used by most fence companies. That one inch may not sound like much, but if you do the math, you’ll find that it works out to about 50% more wood per post!
