Damper trimming

[William R. Monroe]

James,

Good question.  I have trimmed a number of sets, all with positive results.
I would guess that the reason has to do with margin of error.  When you
start trimming dampers close to the contact point, if you
slip..........yikes.  So in the factory, err on the side of caution, leave
'em longer, and let the field techs trim them to satisfy the customer's
complaints of whooshing.  Plus, trimming in the factory would add another
step - until they start manufacturing the damper sets to be shorter.
