“Hello, I am interested in installing a cedar split rail fence around my home, but am concerned about setting the posts in our very heavy clay. I am a contractor and would be concerned about the longevity of the posts with the probability of water collecting and standing in the holes. Is there a way to protect the post below grade? If post spacing is 10′, will the fence rail have any sag?” – Customer Inquiry

How Do You Prevent Fence Rail Sag?
You can’t, but you can install heavier rails to begin with. Our western red split rail products are available in industry standard sizes of jumbo (14-16″ girth), standard (12-14″ girth), and pony (10-12″ girth). Our posts are also jumbo. Line posts and end posts measure approximately 18″, and corners are 20″. Using the heavier grade is the best way to prevent rail sag. We also prefer to only offer our pony size split rail in 8′ lengths to help prevent sag.

For best results, choose larger components when available, backfill with gravel instead of dirt, and use proper sealant, or stain every couple years to prolong the life of your fence. Understand too, labor to install is a constant in this case – meaning it takes nearly the same amount of time to install lesser materials as the best of materials. We’ve found from experience that it is always best to install the best materials available.
