    Homemade dampers

    Hundreds of dampers looked like this. Outlets/inlets nearest the RTU were 200% of design, with damper closed. At the end of the long, meandering ductwork, 50% of design. Contractors were rushing to meet "hard deadlines". This, along with major leaks in ductwork. We just had to say, "sorry, we can't balance it" and let the poop hit the fan until enough band-aid fixes could be done. That was an interesting job....Name:  C104.07 20200612_091822.jpg

    Why buy it, when you can build it yourself!?

    Pretty sure the only quadrant dampers I've ever seen just consist of the ends and you fabricate the rest. Looks like they just used whatever they could hack together on the job.

    These contractors are notorious around here. They make every possible effort to take shortcuts.

    The inspector wanted to see balancing damper (handles) on each branch. He saw them.
    Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.
