  • Applies to SP and NP Profiles only. Not available for WP Profile.
  • Damper is manufactured so that the finished outside frame dimensions are ½” (12.7 mm) smaller than specified opening width & height dimensions.
  • Linkage must remain accessible after installation.
  • In Duct Install Type, single section dampers are constructed with a 2" (51 mm) flange behind the linkage and a ¾" (19 mm) flange at the front of the linkage, to facilitate access from the face side of the damper.
  • Linkage for multi-section dampers is located where damper sections meet and can be accessed from the face side of the damper assembly.
  • TAMCO recommends that Series 9000 BF dampers should not be ordered as In Duct Install Type. Duct work will create a thermal bridge, thereby eliminating the effectiveness and purpose of the thermal break in the damper frame.
  • Always provide opening width and height dimensions, when ordering. Width dimension is always parallel to blades. Height dimension is always perpendicular to blades.
