  • Supplementry Information

  • “A” width and “B” height are opening dimensions. Dampers are provided ¼” undercut.

  • Depending upon damper height, a variable width blade may be required, which will extend to a maximum of 3¼ from either the front or back of the damper If the exact dimensions of this variable blade is critical contact the factory.
