Sometimes Stock Won’t Work

We get that. As a matter of fact, Volko is known for our custom work.

So what can we customize?

Duct Opening: This is the most common part of the wood vent that we make changes to. The smallest duct opening we can do is 2″, and the largest for one vent we can do is 48″. Need bigger? We can make the vent in multiple pieces.

Flange Size: Our standard size flange is 3/4″. Sometimes you need a larger flange to make installation easier. Sometimes you need a smaller flange to fit a tight space. We do this all the time!

Flange Removal: We can also cut a flange or two off in order to fit into tighter spaces.

Neck Removal: Somtimes the “neck” on the vent can impede installation. We can sand that off no problem.

Squared Off Shoulder: Our standard vents are rounded over, but we can make them with a “square shoulder” no problem.

Adjustable Dampers Available on Stock Size Insert Trimline Vents

Box Damper

Box Dampers are the traditional style damper installed on wood vents. The damper extends into the duct, and a small arm protrudes through the face of the vent to open and close the vanes.

This picture shows the actual vanes of the box damper.

EZ Slide Damper

The Easy Slide Damper got it’s name from it’s simplified function and easy attachment.

The metal damper self attaches to guide rails on the Trimline Insert and Flush with Frame vents (standard sizes only). The design allows for airflow control while staying above the duct opening for simplified installation.

Note the vent has to be removed from the floor in order to adjust the damper.

WoodVent Free Air Flow

Wood Vents are more restrictive than metal air registers with the same duct size. This usually is not a problem, but we can always discuss any concerns you may have or special applications with our engineers.

For the Trimline style wood vents, there is a 60% reduction in free area caused by the vent louvers. This means a 10×10 duct will have 40 square inches of free area once a trimline vent is installed.

Again, feel free to call for any assistance with air velocities and sizing.
