Post and rail fencing relies on rail dimensions and post spacing to hold its shape. The wood rails in this category form those spans; their length and cross section need to suit the intended layout rather than simply fill the gap between posts. In the United States, local zoning rules can affect fence height and setbacks, so establish the permitted boundary position before setting out the rails.

Fence Rails

Timber fence rails need an outdoor specification suited to their exposure. Hardwood fence rails vary by species, while pine fence rails require attention to the treatment specified for the intended use. Check the product information for durability and fastening requirements, including how to protect cut ends. A rail carrying vertical fence boards also needs to support their weight and the wind loads on the completed fence.

How should a post and rail fence follow a sloping yard?

Choose between rails that follow the slope and level sections that step down between posts. Mark the proposed rail heights on site to check the gaps beneath the fence before cutting.

Can wood rails connect to posts used for steel fencing?

Confirm that the post manufacturer permits the connection and specifies suitable hardware. Fence rail brackets must fit the rail section and provide an attachment suited to the post material.

What should be checked before replacing a damaged rail?

Inspect the adjoining posts for decay or movement before fitting a replacement. Match the existing rail profile and attachment method unless the original detail contributed to the failure.
