Damper Door Assembly with Locking Knob


The Damper Door Assembly allows easy, customized adjustment of the airflow resistance. The settings range from lowest at #1 with door closed incrementally up to highest at #7 with door fully opened.



Replacement system includes: Damper Door, Hinge Block, Locking Knob, and mounting hardware.

Replacement system was redesigned in early 2012 and is compatible with all Ergs.  The adjustable locking knob system replaces the prior “locking pin” system.  If the Damper Door on your Vasa Ergometer no longer stays set on any given resistance setting, the new system will solve that problem.  Replacement will take approximately 15 minutes.
