Snap-On Control Damper 12 in
The Value Brand snap-on control damper fits a 12 in nominal duct diameter for HVAC airflow regulation. Steel construction provides durability in residential or light commercial ductwork. The round profile allows quick installation without additional framing or fasteners. It suits installers who need a straightforward volume control device.
Installers needing manual balancing
This damper serves technicians balancing forced-air systems where a 12 in round duct requires adjustable airflow up to 1200 fpm. The snap-on design speeds retrofits on existing steel duct runs. It is not for systems needing motorised actuation or automatic zone control. Buyers who want integrated actuators or remote operation should look at motorised alternatives.
Maximum air velocity 1200 fpm
The 1200 fpm velocity rating defines the upper limit for reliable damper operation without excessive noise or pressure drop. Exceeding this figure risks flutter, increased leakage and premature wear on the steel blades. Specifiers must verify design airflow stays at or below this threshold before selecting the part. It is the single figure that confirms suitability for the intended duct run.

Questions about this item
How do I snap the 12 in damper onto the duct without bending the blades?
Align the collar with the duct end, press evenly around the perimeter until the spring tabs click, then verify blades rotate freely before sealing the joint.
Will the steel blades or spring tabs need periodic lubrication or replacement?
The damper has no lubrication points; inspect blades annually for corrosion or binding and replace the entire unit if corrosion appears.
At what airflow does the 1200 fpm limit start to cause noise or blade flutter?
Sustained velocities above 1200 fpm increase turbulence and blade vibration, so size the fan to stay at or below that rating.
