Poly-Vent can be mounted to a variety of materials
including roll-formed rails, hat channels, square or
rectangle tubing, dimensional lumber, and many
other types of rails. The spacing for the rails is the
same, no matter what the application. The spacing
is also the same for either single or stacked applications.
See the chart above to determine the correct spacing
for your Poly-Vent system.
