No. For engineering reasons, the center duct chase opening must remain close to the physical center of the truss. Beginning July 1, 1996 new ANSI standards went into effect for wood floor truss design. ANSI standards do not allow the duct chase to be off-center by more than 12 inches even in custom manufactured trusses.
