Cant Rails
2.4m & 3.6mlong -  Pressure treated Brown
 
The rails have a bevelled / angled edge thats designed so rain water wont sit on the rail.
We recommend using cant rail when your constructing a closeboard fence.
The reference to (2ex) means the rails are cut from a 125mm x 47mm section of timber, therefore creating 2 rails from 1 section of timber. 
The Cant rail finishes up approx 75mm x 47mm with a chamfered edge.
