TL;DR
A bottom rail is the lowest horizontal framing member of a fence panel or gate, tying the pickets together near grade and resisting the sag that gravity works into every span. Wood fences typically run a 2x4 between posts, kept 2 or more inches above grade so the rail does not wick ground moisture; vinyl and aluminum systems use a reinforced channel that often hides a metal stiffener.
What it means
A bottom rail is the lowest horizontal framing member of a fence panel or gate, tying the pickets together near grade and resisting the sag that gravity works into every span. Wood fences typically run a 2x4 between posts, kept 2 or more inches above grade so the rail does not wick ground moisture; vinyl and aluminum systems use a reinforced channel that often hides a metal stiffener. Pool-barrier codes add a dimension: the ISPSC limits the gap under the fence to 2 inches over solid surfaces and 4 over grass. Gates rack without a rigid one, which is why sagging gates get a diagonal brace from its end up to the top hinge.
