Tech Tip
by Michael Slavin, RPT

Occasionally it is necessary to install a heating bar directly in the action as part of a Dampp-Chaser system to control specific humidity related problems in that area, such as tight centers, rust accumulation, or pin-block exposure to extremes. Usually the clips for the heat rod are mounted at the breaks in the keyboard, elevated by long screws and stand-offs to clear the keysticks. These stand-offs are no longer available from Dampp-Chaser. I have found that standard brass refill tubes for toilet tank floats/ballcocks (1/4-inch O.D.) available at all hardware and plumbing supplies are the ideal substitute. The inner diameter perfectly accepts the 2-inch screws supplied by Dampp-Chaser to mount H-2 humidistats (which also fit through the hole in the clips) and the soft brass is easy to cut to the desired length.
